@section Summary
@cindex summary
Org-mode is a mode for keeping notes, maintaining ToDo lists, and doing
project planning with a fast and effective plain-text system.
Org-mode develops organizational tasks around NOTES files that contain
information about projects as plain text. Org-mode is implemented on
top of outline-mode, which makes it possible to keep the content of
large files well structured. Visibility cycling and structure editing
help to work with the tree. Tables are easily created with a built-in
table editor. Org-mode supports ToDo items, deadlines, time stamps,
and scheduling. It dynamically compiles entries into an agenda that
utilizes and smoothly integrates much of the Emacs calendar and diary.
Plain text URL-like links connect to websites, emails, Usenet
messages, BBDB entries, and any files related to the projects. For
printing and sharing of notes, an Org-mode file can be exported as a
structured ASCII file, as HTML, or (todo and agenda items only) as an
iCalendar file. It can also serve as a publishing tool for a set of
linked webpages.
Org-mode keeps simple things simple. When first fired up, it should
feel like a straightforward, easy to use outliner. Complexity is not
imposed, but a large amount of functionality is available when you need
it. Org-mode can be used on different levels and in different ways, for
example:
@example
@r{@bullet{} as an outline extension with visibility cycling and structure editing}
@r{@bullet{} as an ASCII system and table editor for taking structured notes}
@r{@bullet{} as an ASCII table editor with spreadsheet-like capabilities}
@r{@bullet{} as a TODO list editor}
@r{@bullet{} as a full agenda and planner with deadlines and work scheduling}
@r{@bullet{} as a simple hypertext system, with HTML export}
@r{@bullet{} as a publishing tool to create a set of interlinked webpages}
@end example
The Org-mode table editor can be integrated into any major mode by
activating the minor Orgtbl-mode.
@cindex FAQ
There is a website for Org-mode which provides links to the newest
version of Org-mode, as well as additional information, frequently asked
questions (FAQ), links to tutorials etc. This page is located at

@node Installation, Activation, Summary, Introduction
@section Installation
@cindex installation
@cindex XEmacs
@b{Important:} If Org-mode is part of the Emacs distribution or an
XEmacs package, please skip this section and go directly to
@ref{Activation}.
If you have downloaded Org-mode from the Web, you must take the
following steps to install it: Go into the Org-mode distribution
directory and edit the top section of the file @file{Makefile}. You
must set the name of the Emacs binary (likely either @file{emacs} or
@file{xemacs}), and the paths to the directories where local Lisp and
Info files are kept. If you don't have access to the system-wide
directories, create your own two directories for these files, enter them
into the Makefile, and make sure Emacs finds the Lisp files by adding
the following line to @file{.emacs}:
@example
(setq load-path (cons "~/path/to/lispdir" load-path))
@end example
@b{XEmacs users now need to install the file @file{noutline.el} from
the @file{xemacs} subdirectory of the Org-mode distribution. Use the
command:}
@example
@b{make install-noutline}
@end example
@noindent Now byte-compile and install the Lisp files with the shell
commands:
@example
make
make install
@end example
@noindent If you want to install the info documentation, use this command:
@example
make install-info
@end example
@noindent Then add to @file{.emacs}:
@lisp
;; This line only if org-mode is not part of the X/Emacs distribution.
(require 'org-install)
@end lisp
@node Activation, Feedback, Installation, Introduction
@section Activation
@cindex activation
@cindex autoload
@cindex global keybindings
@cindex keybindings, global
Add the following lines to your @file{.emacs} file. The last two lines
define @emph{global} keys for the commands @command{org-store-link} and
@command{org-agenda} - please choose suitable keys yourself.
@lisp
;; The following lines are always needed. Choose your own keys.
(add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
(define-key global-map "\C-cl" 'org-store-link)
(define-key global-map "\C-ca" 'org-agenda)
@end lisp
Furthermore, you must activate @code{font-lock-mode} in org-mode
buffers, because significant functionality depends on font-locking being
active. You can do this with either one of the following two lines
(XEmacs user must use the second option):
@lisp
(global-font-lock-mode 1) ; for all buffers
(add-hook 'org-mode-hook 'turn-on-font-lock) ; org-mode buffers only
@end lisp
@cindex org-mode, turning on
With this setup, all files with extension @samp{.org} will be put
into Org-mode. As an alternative, make the first line of a file look
like this:
@example
MY PROJECTS -*- mode: org; -*-
@end example
@noindent which will select Org-mode for this buffer no matter what
the file's name is. See also the variable
@code{org-insert-mode-line-in-empty-file}.

@cindex bug reports
@cindex maintainer
@cindex author
If you find problems with Org-mode, or if you have questions, remarks,
or ideas about it, please contact the maintainer @value{MAINTAINER} at
@value{MAINTAINEREMAIL}.
For bug reports, please provide as much information as possible,
including the version information of Emacs (@kbd{C-h v emacs-version
@key{RET}}) and Org-mode (@kbd{C-h v org-version @key{RET}}), as well as
the Org-mode related setup in @file{.emacs}. If an error occurs, a
traceback can be very useful. Often a small example file helps, along
with clear information about:
@enumerate
@item What exactly did you do?
@item What did you expect to happen?
@item What happened instead?
@end enumerate
@noindent Thank you for helping to improve this mode.

@node Outlines, Headlines, Document structure, Document structure
@section Outlines
@cindex outlines
@cindex outline-mode
Org-mode is implemented on top of outline-mode. Outlines allow to
organize a document in a hierarchical structure, which (at least for
me) is the best representation of notes and thoughts. Overview over
this structure is achieved by folding (hiding) large parts of the
document to show only the general document structure and the parts
currently being worked on. Org-mode greatly simplifies the use of
outlines by compressing the entire show/hide functionality into a
single command @command{org-cycle}, which is bound to the @key{TAB}
key.
@node Headlines, Visibility cycling, Outlines, Document structure
@section Headlines
@cindex headlines
@cindex outline tree
Headlines define the structure of an outline tree. The headlines in
Org-mode start with one or more stars, on the left margin. For
example:
@example
* Top level headline
** Second level
*** 3rd level
some text
*** 3rd level
more text
* Another top level headline
@end example
@noindent Some people find the many stars too noisy and would prefer an
outline that has whitespace followed by a single star as headline
starters. @ref{Clean view} describes a setup to realize this.
@node Visibility cycling, Motion, Headlines, Document structure
@section Visibility cycling
@cindex cycling, visibility
@cindex visibility cycling
@cindex trees, visibility
@cindex show hidden text
@cindex hide text
Outlines make it possible to hide parts of the text in the buffer.
Org-mode uses just two commands, bound to @key{TAB} and
@kbd{S-@key{TAB}} to change the visibility in the buffer.
@cindex subtree visibility states
@cindex subtree cycling
@cindex folded, subtree visibility state
@cindex children, subtree visibility state
@cindex subtree, subtree visibility state
@table @kbd
@kindex @key{TAB}
@item @key{TAB}
@emph{Subtree cycling}: Rotate current subtree between the states
@example
,-> FOLDED -> CHILDREN -> SUBTREE --.
'-----------------------------------'
@end example
The cursor must be on a headline for this to work@footnote{see, however,
the option @code{org-cycle-emulate-tab}.}. When the cursor is at the
beginning of the buffer and the first line is not a headline, then
@key{TAB} actually runs global cycling (see below)@footnote{see the
option @code{org-cycle-global-at-bob}.}. Also when called with a prefix
argument (@kbd{C-u @key{TAB}}), global cycling is invoked.
@cindex global visibility states
@cindex global cycling
@cindex overview, global visibility state
@cindex contents, global visibility state
@cindex show all, global visibility state
@kindex S-@key{TAB}
@item S-@key{TAB}
@itemx C-u @key{TAB}
@emph{Global cycling}: Rotate the entire buffer between the states
@example
,-> OVERVIEW -> CONTENTS -> SHOW ALL --.
'--------------------------------------'
@end example
Note that inside tables, @kbd{S-@key{TAB}} jumps to the previous field.
@cindex show all, command
@kindex C-c C-a
@item C-c C-a
Show all.
@end table
When Emacs first visits an Org-mode file, the global state is set to
OVERVIEW, i.e. only the top level headlines are visible. This can be
configured through the variable @code{org-startup-folded}, or on a
per-file basis by adding one of the following lines anywhere in the
buffer:
@example
#+STARTUP: overview
#+STARTUP: content
#+STARTUP: showall
@end example
@node Motion, Structure editing, Visibility cycling, Document structure
@section Motion
@cindex motion, between headlines
@cindex jumping, to headlines
@cindex headline navigation
The following commands jump to other headlines in the buffer.
@table @kbd
@kindex C-c C-n
@item C-c C-n
Next heading.
@kindex C-c C-p
@item C-c C-p
Previous heading.
@kindex C-c C-f
@item C-c C-f
Next heading same level.
@kindex C-c C-b
@item C-c C-b
Previous heading same level.
@kindex C-c C-u
@item C-c C-u
Backward to higher level heading.
@kindex C-c C-j
@item C-c C-j
Jump to a different place without changing the current outline
visibility. Shows the document structure in a temporary buffer, where
you can use visibility cycling (@key{TAB}) to find your destination.
After pressing @key{RET}, the cursor moves to the selected location in
the original buffer, and the headings hierarchy above it is made
visible.

@table @kbd
@kindex M-@key{RET}
@item M-@key{RET}
Insert new heading with same level as current. If the cursor is in a
plain list item, a new item is created (@pxref{Plain lists}). To force
creation of a new headline, use a prefix arg, or first press @key{RET}
to get to the beginning of the next line. When this command is used in
the middle of a line, the line is split and the rest of the line becomes
the new headline. If the command is used at the beginning of a
headline, the new headline is created before the current line. If at
the beginning of any other line, the content of that line is made the
new heading.
@kindex M-S-@key{RET}
@item M-S-@key{RET}
Insert new TODO entry with same level as current heading.
@kindex M-@key{left}
@item M-@key{left}
Promote current heading by one level.
@kindex M-@key{right}
@item M-@key{right}
Demote current heading by one level.
@kindex M-S-@key{left}
@item M-S-@key{left}

@kindex M-S-@key{up}
@item M-S-@key{up}
Move subtree up (swap with previous subtree of same
level).
@kindex M-S-@key{down}
@item M-S-@key{down}
Move subtree down (swap with next subtree of same level).
@kindex C-c C-x C-w
@kindex C-c C-x C-k
@item C-c C-x C-w
@itemx C-c C-x C-k
Kill subtree, i.e. remove it from buffer but save in kill ring.
@kindex C-c C-x M-w
@item C-c C-x M-w
Copy subtree to kill ring.
@kindex C-c C-x C-y
@item C-c C-x C-y
Yank subtree from kill ring. This does modify the level of the subtree to
make sure the tree fits in nicely at the yank position. The yank
level can also be specified with a prefix arg, or by yanking after a
headline marker like @samp{****}.
@end table
@cindex region, active
@cindex active region
@cindex transient-mark-mode
When there is an active region (transient-mark-mode), promotion and
demotion work on all headlines in the region. To select a region of
headlines, it is best to place both point and mark at the beginning of a
line, mark at the beginning of the first headline, and point at the line
just after the last headline to change. Note that when the cursor is
inside a table (@pxref{Tables}), the Meta-Cursor keys have different
functionality.
@node Archiving, Sparse trees, Structure editing, Document structure
@section Archiving
@cindex archiving
When a project represented by a (sub)tree is finished, you may want
to move the tree out of the way and to stop it from contributing to the
agenda. Org-mode knows two ways of archiving. You can mark a tree with
the ARCHIVE tag, or you can move an entire (sub)tree to a different
location.
@menu
* ARCHIVE tag:: Marking a tree as inactive
* Moving subtrees:: Moving a tree to an archive file
@end menu
@node ARCHIVE tag, Moving subtrees, Archiving, Archiving
@subsection The ARCHIVE tag
@cindex internal archiving
A headline that is marked with the ARCHIVE tag (@pxref{Tags}) stays at
its location in the outline tree, but behaves in the following way:
@itemize @minus
@item
It does not open when you attempt to do so with a visibility cycling
command (@pxref{Visibility cycling}). You can still open it with a
normal outline command like @code{show-all}. Or you can modify the
option @code{org-cycle-open-archived-trees}.
@item
During sparse tree construction (@pxref{Sparse trees}), matches in
archived subtrees are not exposed, unless you configure the option
@code{org-sparse-tree-open-archived-trees}.
@item
During agenda view construction (@pxref{Agenda views}), the content of
archived trees is ignored unless you configure the option
@code{org-agenda-skip-archived-trees}.
@item
Archived trees are not exported (@pxref{Exporting}), only the headline
is. Configure the details using the variable
@code{org-export-with-archived-trees}.
@end itemize
The following commands allow to set or clear the ARCHIVE tag:
@table @kbd
@kindex C-c C-x C-a
@item C-c C-x C-a
Toggle the ARCHIVE tag for the current headline. When the tag is set,
the headline changes to a shadowish face, and the subtree below it is
hidden.
@kindex C-u C-c C-x C-a
@item C-u C-c C-x C-a
Check if any direct children of the current headline should be archived.
To do this, each subtree is checked for open TODO entries. If none are
found, the command offers to set the ARCHIVE tag for the child. If the
cursor is @emph{not} on a headline when this command is invoked, the
level 1 trees will be checked.
@end table
@node Moving subtrees, , ARCHIVE tag, Archiving
@subsection Moving subtrees
@cindex external archiving
Once an entire project is finished, you may want to move it to a
different location, either in the current file, or even in a different
file, the archive file.
@table @kbd
@kindex C-c $
@item C-c $
Archive the subtree starting at the cursor position to the location
given by @code{org-archive-location}.
@kindex C-u C-c $
@item C-u C-c $
Check if any direct children of the current headline could be moved to
the archive. To do this, each subtree is checked for open TODO entries.
If none are found, the command offers to move it to the archive
location. If the cursor is @emph{not} on a headline when this command
is invoked, the level 1 trees will be checked.
@end table
@cindex archive locations
The default archive location is a file in the same directory as the
current file, with the name derived by appending @file{_archive} to the
current file name. For information and examples on how to change this,
see the documentation string of the variable
@code{org-archive-location}.
@node Sparse trees, Plain lists, Archiving, Document structure
@section Sparse trees
@cindex sparse trees
@cindex trees, sparse
@cindex folding, sparse trees
@cindex occur, command
An important feature of Org-mode is the ability to construct
@emph{sparse trees} for selected information in an outline tree. A
sparse tree means that the entire document is folded as much as
possible, but the selected information is made visible along with the
headline structure above it@footnote{See also the variables
@code{org-show-hierarchy-above} and
@code{org-show-following-heading}.}. Just try it out and you will see
immediately how it works.
Org-mode contains several commands creating such trees. The most
basic one is @command{org-occur}:
@table @kbd
@kindex C-c /
@item C-c /
Occur. Prompts for a regexp and shows a sparse tree with all matches.
If the match is in a headline, the headline is made visible. If the
match is in the body of an entry, headline and body are made visible.
In order to provide minimal context, also the full hierarchy of
headlines above the match is shown, as well as the headline following
the match. Each match is also highlighted; the highlights disappear
when the buffer is changed with an editing command.
@end table
@noindent
For frequently used sparse trees of specific search strings, you can
use the variable @code{org-agenda-custom-commands} to define fast
keyboard access to specific sparse trees. These commands will then be
accessible through the agenda dispatcher (@pxref{Agenda dispatcher}).
For example:
@lisp
(setq org-agenda-custom-commands
'(("f" occur-tree "FIXME")))
@end lisp
@noindent will define the key @kbd{C-c a f} as a shortcut for creating
a sparse tree matching the string @samp{FIXME}.
Other commands use sparse trees as well. For example @kbd{C-c
C-v} creates a sparse TODO tree (@pxref{TODO basics}).
@kindex C-c C-e v
@cindex printing sparse trees
@cindex visible text, printing
To print a sparse tree, you can use the Emacs command
@code{ps-print-buffer-with-faces} which does not print invisible parts
of the document @footnote{This does not work under XEmacs, because
XEmacs uses selective display for outlining, not text properties.}.
Or you can use the command @kbd{C-c C-e v} to export only the visible
part of the document and print the resulting file.
@node Plain lists, Checkboxes, Sparse trees, Document structure
@section Plain lists
@cindex plain lists
@cindex lists, plain
@cindex lists, ordered
@cindex ordered lists
Headlines define both the structure of the Org-mode file, and also lists
(for example, TODO items (@pxref{TODO items}) should be created using
headline levels). When taking notes, however, the plain text is
sometimes easier to read with hand-formatted lists. Org-mode supports
editing such lists, and the HTML exporter (@pxref{Exporting}) does
parse and format them.
Org-mode knows ordered and unordered lists. Unordered list items start
with @samp{-}, @samp{+}, or @samp{*}@footnote{When using @samp{*} as a
bullet, lines must be indented or they will be seen as top-level
headlines. Also, when you are hiding leading stars to get a clean
outline view, plain list items starting with a star are visually
indistinguishable from true headlines. In short: even though @samp{*}
is supported, it may be better not to use it for plain list items} as
bullets. Ordered list items start with @samp{1.} or @samp{1)}. Items
belonging to the same list must have the same indentation on the first
line. In particular, if an ordered list reaches number @samp{10.}, then
the 2--digit numbers must be written left-aligned with the other numbers
in the list. Indentation also determines the end of a list item. It
ends before the next line that is indented like the bullet/number, or
less. For example:
@example
@group
** Lord of the Rings
My favorite scenes are (in this order)
1. Eowyns fight with the witch king
+ this was already my favorite scene in the book
+ I really like Miranda Otto.
2. The attack of the Rohirrim
3. Peter Jackson being shot by Legolas
- on DVD only
He makes a really funny face when it happens.
But in the end, not individual scenes matter but the film as a whole.
@end group
@end example
Org-mode supports these lists by tuning filling and wrapping commands to
deal with them correctly@footnote{Org-mode only changes the filling
settings for Emacs. For XEmacs, you should use Kyle E. Jones'
@file{filladapt.el}. To turn is on, put into @file{.emacs}:
@example
(require 'filladapt)
@end example
}.
The following commands act on items when the cursor is in the first line
of an item (the line with the bullet or number).
@table @kbd
@kindex @key{TAB}
@item @key{TAB}
Items can be folded just like headline levels if you set the variable
@code{org-cycle-include-plain-lists}. The level of an item is then
given by the indentation of the bullet/number. Items are always
subordinate to real headlines, however; the hierarchies remain
completely separated.
@kindex M-@key{RET}
@item M-@key{RET}
Insert new item at current level. With prefix arg, force a new heading
(@pxref{Structure editing}). If this command is used in the middle of a
line, the line is @emph{split} and the rest of the line becomes the new
item. If this command is executed in the @emph{whitespace before a bullet or
number}, the new item is created @emph{before} the current item. If the
command is executed in the white space before the text that is part of
an item but does not contain the bullet, a bullet is added to the
current line.
@kindex M-S-@key{RET}
@item M-S-@key{RET}
Insert a new item with a checkbox (@pxref{Checkboxes}).
@kindex S-@key{up}
@kindex S-@key{down}
@item S-@key{up}
@itemx S-@key{down}
Jump to the previous/next item in the current list.
@kindex M-S-@key{up}
@kindex M-S-@key{down}
@item M-S-@key{up}
@itemx M-S-@key{down}
Move the item including subitems up/down (swap with previous/next item
of same indentation). If the list is ordered, renumbering is
automatic.
@kindex M-S-@key{left}
@kindex M-S-@key{right}
@item M-S-@key{left}
@itemx M-S-@key{right}
Decrease/increase the indentation of the item, including subitems.
Initially, the item tree is selected based on current indentation.
When these commands are executed several times in direct succession,
the initially selected region is used, even if the new indentation
would imply a different hierarchy. To use the new hierarchy, break
the command chain with a cursor motion or so.
@kindex C-c C-c
@item C-c C-c
If there is a checkbox (@pxref{Checkboxes}) in the item line, toggle the
state of the checkbox. Otherwise, if this is an ordered list, renumber
the ordered list at the cursor.
@end table
@page
@node Checkboxes, , Plain lists, Document structure
@section Checkboxes
@cindex checkboxes
Every item in a plain list (ordered and unordered) can be made a
checkbox by starting it with the string @samp{[ ]}. This feature is
similar to TODO items (@pxref{TODO items}), but more lightweight.
Checkboxes are not included into the global TODO list, so they are often
great to split a task into a number of simple steps. Or you can use
them in a shopping list to select the items you need to buy. To toggle
a checkbox, use @kbd{C-c C-c}, or try Piotr Zielinski's
@file{org-mouse.el}. Here is an example of a checkbox list.
@example
* Avoid stupid mistakes when distributing a new version
- [ ] update also Emacs CVS
- [X] forget to update index.html on the website
- [X] leaving a `(debug)' form in the code
@end example
@noindent The following commands work with checkboxes:
@table @kbd
@kindex C-c C-c
@item C-c C-c
Toggle checkbox at point.
@kindex C-c C-x C-b
@item C-c C-x C-b
Toggle checkbox at point.
@itemize @minus
@item
If there is an active region, toggle the first checkbox in the region
and set all remaining boxes to the same status as the first. If you
want to toggle all boxes in the region independently, use a prefix
argument.
@item
If the cursor is in a headline, toggle checkboxes in the region between
this headline and the next. This does @emph{not} act on the entire
subtree, just the current entry.
@item
If no active region, just toggle the checkbox at point.
@end itemize
@kindex M-S-@key{RET}
@item M-S-@key{RET}
Insert a new item with a checkbox.
This works only if the cursor is already in a plain list item
(@pxref{Plain lists}).

@section The built-in table editor
@cindex table editor, builtin
Org-mode makes it easy to format tables in plain ASCII. Any line with
@samp{|} as the first non-white character is considered part of a
table. @samp{|} is also the column separator. A table might look
like this:
@example
| Name | Phone | Age |
|-------+-------+-----|
| Peter | 1234 | 17 |
| Anna | 4321 | 25 |
@end example
A table is re-aligned automatically each time you press @key{TAB} or
@key{RET} or @kbd{C-c C-c} inside the table. @key{TAB} also moves to
the next field (@key{RET} to the next row) and creates new table rows
at the end of the table or before horizontal lines. The indentation
of the table is set by the first line. Any line starting with
@samp{|-} is considered as a horizontal separator line and will be
expanded on the next re-align to span the whole table width. So, to
create the above table, you would only type
@example
|Name|Phone|Age
|-
@end example
@noindent and then press @key{TAB} to align the table and start filling in
fields.
When typing text into a field, Org-mode treats @key{DEL},
@key{Backspace}, and all character keys in a special way, so that
inserting and deleting avoids shifting other fields. Also, when
typing @emph{immediately after the cursor was moved into a new field
with @kbd{@key{TAB}}, @kbd{S-@key{TAB}} or @kbd{@key{RET}}}, the
field is automatically made blank. If this behavior is too
unpredictable for you, configure the variables
@code{org-enable-table-editor} and @code{org-table-auto-blank-field}.
@table @kbd
@tsubheading{Creation and conversion}
@kindex C-c |
@item C-c |
Convert the active region to table. If every line contains at least one
TAB character, the function assumes that the material is tab separated.
If not, lines are split at whitespace into fields. You can use a prefix
argument to indicate the minimum number of consecutive spaces required
to identify a field separator (default: just one).@*
If there is no active region, this command creates an empty Org-mode
table. But it's easier just to start typing, like
@kbd{|Name|Phone|Age @key{RET} |- @key{TAB}}.
@tsubheading{Re-aligning and field motion}
@kindex C-c C-c
@item C-c C-c
Re-align the table without moving the cursor.
@kindex @key{TAB}
@item @key{TAB}
Re-align the table, move to the next field. Creates a new row if
necessary.
@kindex S-@key{TAB}
@item S-@key{TAB}
Re-align, move to previous field.
@kindex @key{RET}
@item @key{RET}
Re-align the table and move down to next row. Creates a new row if
necessary. At the beginning or end of a line, @key{RET} still does
NEWLINE, so it can be used to split a table.
@tsubheading{Column and row editing}
@kindex M-@key{left}
@kindex M-@key{right}
@item M-@key{left}
@itemx M-@key{right}
Move the current column left/right.
@kindex M-S-@key{left}
@item M-S-@key{left}
Kill the current column.
@kindex M-S-@key{right}
@item M-S-@key{right}
Insert a new column to the left of the cursor position.
@kindex M-@key{up}
@kindex M-@key{down}
@item M-@key{up}
@itemx M-@key{down}
Move the current row up/down.
@kindex M-S-@key{up}
@item M-S-@key{up}
Kill the current row or horizontal line.
@kindex M-S-@key{down}
@item M-S-@key{down}
Insert a new row above (with arg: below) the current row.
@kindex C-c -
@item C-c -
Insert a horizontal line below current row. With prefix arg, the line
is created above the current line.
@kindex C-c ^
@item C-c ^
Sort the table lines in the region. Point and mark must be in the first
and last line to be included, and must be in the column that should be
used for sorting. The command prompts for numerical versus
alphanumerical sorting.
@tsubheading{Regions}
@kindex C-c C-x M-w
@item C-c C-x M-w
Copy a rectangular region from a table to a special clipboard. Point
and mark determine edge fields of the rectangle. The process ignores
horizontal separator lines.
@kindex C-c C-x C-w
@item C-c C-x C-w
Copy a rectangular region from a table to a special clipboard, and
blank all fields in the rectangle. So this is the ``cut'' operation.
@kindex C-c C-x C-y
@item C-c C-x C-y
Paste a rectangular region into a table.
The upper right corner ends up in the current field. All involved fields
will be overwritten. If the rectangle does not fit into the present table,
the table is enlarged as needed. The process ignores horizontal separator
lines.
@kindex C-c C-q
@item C-c C-q
Wrap several fields in a column like a paragraph. If there is an active
region, and both point and mark are in the same column, the text in the
column is wrapped to minimum width for the given number of lines. A
prefix ARG may be used to change the number of desired lines. If there
is no region, the current field is split at the cursor position and the
text fragment to the right of the cursor is prepended to the field one
line down. If there is no region, but you specify a prefix ARG, the
current field is made blank, and the content is appended to the field
above.
@tsubheading{Calculations}
@cindex formula, in tables

@kindex C-c =
@item C-c =

@kindex C-c '
@item C-c '
Edit all formulas associated with the current table in a separate

Recalculate the current row by applying the stored formulas from left

entire table, starting with the first non-header line (i.e. below the
first horizontal separator line). For details, see @ref{Table calculations}.
@kindex C-#
@item C-#
Rotate the calculation mark in first column through the states
@samp{}, @samp{#}, @samp{*}, @samp{!}, @samp{$}. For the meaning of
these marks see @ref{Advanced features}. When there is an active

be inserted with @kbd{C-y}.
@kindex S-@key{RET}
@item S-@key{RET}
When current field is empty, copy from first non-empty field above.
When not empty, copy current field down to next row and move cursor
along with it. Depending on the variable
@code{org-table-copy-increment}, integer field values will be
incremented during copy. This key is also used by CUA-mode
(@pxref{Cooperation}).
@tsubheading{Miscellaneous}
@kindex C-c `
@item C-c `
Edit the current field in a separate window. This is useful for fields
that are not fully visible (@pxref{Narrow columns}). When called with a
@kbd{C-u} prefix, just make the full field visible, so that it can be
edited in place.
@kindex C-c @key{TAB}
@item C-c @key{TAB}
This is an alias for @kbd{C-u C-c `} to make the current field fully
visible.
@item M-x org-table-import
Import a file as a table. The table should be TAB- or whitespace
separated. Useful, for example, to import an Excel table or data from a
database, because these programs generally can write TAB-separated text
files. This command works by inserting the file into the buffer and
then converting the region to a table. Any prefix argument is passed on
to the converter, which uses it to determine the separator.
@item M-x org-table-export
Export the table as a TAB-separated file. Useful for data exchange with,
for example, Excel or database programs.
@end table
If you don't like the automatic table editor because it gets in your
way on lines which you would like to start with @samp{|}, you can turn
it off with
@lisp
(setq org-enable-table-editor nil)
@end lisp
@noindent Then the only table command that still works is
@kbd{C-c C-c} to do a manual re-align.
@node Narrow columns, Table calculations, Built-in table editor, Tables
@section Narrow columns
@cindex narrow columns in tables
The width of columns is automatically determined by the table editor.
Sometimes a single field or a few fields need to carry more text,
leading to inconveniently wide columns. To limit@footnote{This feature
does not work on XEmacs.} the width of a column, one field anywhere in
the column may contain just the string @samp{<N>} where @samp{N} is an
integer specifying the width of the column in characters. The next
re-align will then set the width of this column to no more than this
value.
@example
|---+------------------------------| |---+--------|
| | | | | <6> |
| 1 | one | | 1 | one |
| 2 | two | ----\ | 2 | two |
| 3 | This is a long chunk of text | ----/ | 3 | This=> |
| 4 | four | | 4 | four |
|---+------------------------------| |---+--------|
@end example
@noindent
Fields that are wider become clipped and end in the string @samp{=>}.
Note that the full text is still in the buffer, it is only invisible.
To see the full text, hold the mouse over the field - a tooltip window
will show the full content. To edit such a field, use the command
@kbd{C-c `} (that is @kbd{C-c} followed by the backquote). This will
open a new window with the full field. Edit it and finish with @kbd{C-c
C-c}.
When visiting a file containing a table with narrowed columns, the
necessary character hiding has not yet happened, and the table needs to
be aligned before it looks nice. Setting the option
@code{org-startup-align-all-tables} will realign all tables in a file
upon visiting, but also slow down startup. You can also set this option
on a per-file basis with:
@example
#+STARTUP: align
#+STARTUP: noalign

@cindex spreadsheet capabilities
@cindex @file{calc} package
The table editor makes use of the Emacs @file{calc} package to implement
spreadsheet-like capabilities. It can also evaluate Emacs Lisp forms to
derive fields from other fields. Org-mode has two levels of complexity
for table calculations. On the basic level, tables do only horizontal
computations, so a field can be computed from other fields @emph{in the
same row}, and Org-mode assumes that there is only one formula for each
column. This is very efficient to work with and enough for many tasks.
On the complex level, columns and individual fields can be named for
easier referencing in formulas, individual named fields can have their
own formula associated with them, and recalculation can be automated.

@cindex formula syntax
@cindex syntax, of formulas
A formula can be any algebraic expression understood by the Emacs
@file{calc} package. Note that @file{calc} has the slightly
non-standard convention that @samp{/} has lower precedence than
@samp{*}, so that @samp{a/b*c} is interpreted as @samp{a/(b*c)}. Before
evaluation by @code{calc-eval} (@pxref{Calling Calc from Your
Programs,calc-eval,Calling calc from Your Lisp Programs,calc,GNU Emacs
Calc Manual}), variable substitution takes place:
@example
$ @r{refers to the current field}
$3 @r{refers to the field in column 3 of the current row}
$3..$7 @r{a vector of the fields in columns 3-7 of current row}
$P1..$P3 @r{vector of column range, using column names}
&2 @r{second data field above the current, in same column}
&5-2 @r{vector from fifth to second field above current}
&III-II @r{vector of fields between 2nd and 3rd hline above}
&III @r{vector of fields between third hline above and current field}
$name @r{a named field, parameter or constant}
@end example
@cindex vectors, in table calculations
The range vectors can be directly fed into the calc vector functions
like @samp{vmean} and @samp{vsum}.
@cindex name, of column or field
@cindex constants, in calculations
@samp{$name} is interpreted as the name of a column, parameter or
constant. Constants are defined globally through the variable
@code{org-table-formula-constants}. If you have the
@file{constants.el} package, it will also be used to resolve
constants, including natural constants like @samp{$h} for Planck's
constant, and units like @samp{$km} for kilometers. Column names and
parameters can be specified in special table lines. These are
described below, see @ref{Advanced features}.
@cindex format specifier
@cindex mode, for @file{calc}
A formula can contain an optional mode string after a semicolon. This
string consists of flags to influence calc's modes@footnote{By
default, Org-mode uses the standard calc modes (precision 12, angular
units degrees, fraction and symbolic modes off). The display format,
however, has been changed to @code{(float 5)} to keep tables compact.
The default settings can be configured using the variable
@code{org-calc-default-modes}.} during execution, e.g. @samp{p20} to
switch the internal precision to 20 digits, @samp{n3}, @samp{s3},
@samp{e2} or @samp{f4} to switch to normal, scientific, engineering,
or fixed display format, respectively, and @samp{D}, @samp{R}, @samp{F},
and @samp{S} to turn on degrees, radians, fraction and symbolic modes,
respectively. In addition, you may provide a @code{printf} format
specifier to reformat the final result. A few examples:
@example
$1+$2 @r{Sum of first and second field}
$1+$2;%.2f @r{Same, format result to two decimals}
exp($2)+exp($1) @r{Math functions can be used}
$;%.1f @r{Reformat current cell to 1 decimal}
($3-32)*5/9 @r{Degrees F -> C conversion}
$c/$1/$cm @r{Hz -> cm conversion, using @file{constants.el}}
tan($1);Dp3s1 @r{Compute in degrees, precision 3, display SCI 1}
sin($1);Dp3%.1e @r{Same, but use printf specifier for display}
vmean($2..$7) @r{Compute column range mean, using vector function}
vsum(&III) @r{Sum numbers from 3rd hline above, up to here}
taylor($3,x=7,2) @r{taylor series of $3, at x=7, second degree}
@end example

@cindex Lisp forms, as table formulas
It is also possible to write a formula in Emacs lisp; this can be useful
for string manipulation and control structures. If a formula starts
with a single quote followed by an opening parenthesis, then it is
evaluated as a lisp form. The evaluation should return either a string
or a number. Just as with @file{calc} formulas, you can provide a
format specifier after a semicolon. A few examples:
@example
@r{swap the first two characters of the content of column 1}
'(concat (substring "$1" 1 2) (substring "$1" 0 1) (substring "$1" 2))
@r{Add columns 1 and 2, equivalent to the calc's @code{$1+$2}}

@end example
@node Column formulas, Advanced features, Lisp formulas, Table calculations
@subsection Column formulas
@cindex column formula
@cindex formula, for table column
To apply a formula to a field, type it directly into the field,
preceded by an equal sign, like @samp{=$1+$2}. When you press
@key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the
field, the formula will be stored as the formula for the current
column, evaluated and the current field replaced with the result. If
the field contains only @samp{=}, the previously stored formula for
this column is used.
For each column, Org-mode will remember the most recently used
formula. The information is stored in a special line starting with
@samp{#+TBLFM} directly below the table. When adding/deleting/moving
columns with the appropriate commands, the stored equations will be
modified accordingly. When a column used in a calculation is removed,
references to this column become invalid and will cause an error upon
applying the equation.
Instead of typing an equation into the field, you may also use the
command @kbd{C-c =}. It prompts for a formula (with default taken
from the @samp{#+TBLFM:} line) and applies it to the current field. A
numerical prefix (e.g. @kbd{C-5 C-c =}) will apply it to that many
consecutive fields in the current column.
@cindex recomputing table fields
To recompute all the fields in a line, use the command @kbd{C-c *}.
It re-applies all stored equations to the current row, from left to
right. With a @kbd{C-u} prefix, this will be done to every line in
the table, so use this command it you want to make sure the entire
table is up-to-date. @kbd{C-u C-c C-c} is another way to update the
entire table. Global updating does not touch the line(s) above the
first horizontal separator line, assuming that this is the table
header.
@node Advanced features, Named-field formulas, Column formulas, Table calculations
@subsection Advanced features
If you want the recalculation of fields to happen automatically,
or if you want to be able to assign a formula to an individual field
(instead of an entire column) you need to reserve the first column of
the table for special marking characters. Here is an example of a
table that collects exam results of students and makes use of these
features:
@example
@group
|---+---------+--------+--------+--------+-------+------|

|---+---------+--------+--------+--------+-------+------|
| ! | | P1 | P2 | P3 | Tot | |

@end group
@end example
@noindent @b{Important}: Please note that for these special tables,
recalculating the table with @kbd{C-u C-c *} will only affect rows
that are marked @samp{#} or @samp{*}, and named fields. The column
formulas are not applied in rows with empty first field.
@cindex marking characters, tables
The marking characters have the following meaning:
@table @samp
@item !
The fields in this line define names for the columns, so that you may
refer to a column as @samp{$Tot} instead of @samp{$6}.
@item ^
This row defines names for the fields @emph{above} the row. With such
a definition, any formula in the table may use @samp{$m1} to refer to
the value @samp{10}. Also, named fields can have their own formula
associated with them.
@item _
Similar to @samp{^}, but defines names for the fields in the row
@emph{below}.
@item $
Fields in this row can define @emph{parameters} for formulas. For
example, if a field in a @samp{$} row contains @samp{max=50}, then
formulas in this table can refer to the value 50 using @samp{$max}.
Parameters work exactly like constants, only that they can be defined on
a per-table basis. Changing a parameter and then recalculating the
table can be useful.
@item #
Fields in this row are automatically recalculated when pressing
@key{TAB} or @key{RET} or @kbd{S-@key{TAB}} in this row. Also, this row
is selected for a global recalculation with @kbd{C-u C-c *}. Unmarked
lines will be left alone by this command.
@item *
Selects this line for global recalculation with @kbd{C-u C-c *}, but
not for automatic recalculation. Use this when automatic
recalculation slows down editing too much.
@item
Unmarked lines are exempt from recalculation with @kbd{C-u C-c *}.
All lines that should be recalculated should be marked with @samp{#}
or @samp{*}.

=} and @kbd{C-u C-c =}, respectively. The currently active expression
is then presented as default in the minibuffer, where it may be edited.
Note that making a table field blank does not remove the formula
associated with the field - during the next recalculation the field
will be filled again. To remove a formula from a field, you have to
give an empty reply when prompted for the formula, or to edit the
@samp{#+TBLFM} line.
@kindex C-c C-c
You may edit the @samp{#+TBLFM} directly and re-apply
the changed equations with @kbd{C-c C-c} in that line, or with the
normal recalculation commands in the table.
@kindex C-c '
@kindex C-c C-c
@kindex C-c C-q
@kindex C-c ?
In particular for large tables with many formulas, it is convenient to
use the command @kbd{C-c '} to edit the formulas of the current table
in a separate buffer. That buffer will show the formulas one per
line, and you are free to edit, add and remove formulas. Press
@kbd{C-c ?} on a @samp{$...} expression to get information about its
interpretation. Exiting the buffer with @kbd{C-c C-c} only stores the
modified formulas below the table. Exiting with @kbd{C-u C-c C-c}
also applies them to the entire table. @kbd{C-c C-q} exits without
installing the changes.
When the evaluation of a formula leads to an error, the field content
becomes the string @samp{#ERROR}. If you would like see what is going
on during variable substitution and calculation in order to find a
bug, turn on formula debugging in the menu and repeat the calculation,
for example by pressing @kbd{C-c = @key{RET}} in a field.
Detailed information will be displayed.

When @key{TAB} or @kbd{C-c C-c} is pressed in such a table, Org-mode
will call @command{table-recognize-table} and move the cursor into the

@cindex format, of links
Org-mode will recognize plain URL-like links and activate them as
clickable links. The general link format, however, looks like this:
@example
[[link][description]] @r{or alternatively} [[link]]
@end example
Once a link in the buffer is complete (all brackets present), Org-mode
will change the display so that @samp{description} is displayed instead
of @samp{[[link][description]]} and @samp{link} is displayed instead of
@samp{[[link]]}. Links will be highlighted in the face @code{org-link},
which by default is an underlined face. You can directly edit the
visible part of a link. Note that this can be either the @samp{link}
part (if there is no description) or the @samp{description} part. To
edit also the invisible @samp{link} part, use @kbd{C-c C-l} with the
cursor on the link.
If you place the cursor at the beginning or just behind the end of the
displayed text and press @key{BACKSPACE}, you will remove the
(invisible) bracket at that location. This makes the link incomplete
and the internals are again displayed as plain text. Inserting the
missing bracket hides the link internals again. To show the
internal structure of all links, use the menu entry
@code{Org->Hyperlinks->Literal links}.

@section Internal links

@cindex links, internal
@cindex CamelCase links
If the link does not look like a URL, it is considered to be internal in
the current file. Links such as @samp{[[My Target]]} or @samp{[[My
Target][Find my target]]} lead to a text search in the current file.
The link can be followed with @kbd{C-c C-o} when the cursor is on the
link, or with a mouse click (@pxref{Handling links}). The preferred
match for such a link is a dedicated target: the same string in double
angular brackets. Targets may be located anywhere; often it is
convenient to put them into a comment line. For example
@example
# <<My Target>>
@end example
@noindent In HTML export (@pxref{HTML export}), such targets will become
named anchors for direct access through @samp{http} links@footnote{Note
that text before the first headline will never be exported, so the first
such target must be after the first headline.}.
If no dedicated target exists, Org-mode will search for the words in the
link. In the above example the search would be for @samp{my target}.
Links starting with a star like @samp{*My Target} restrict the search to
headlines. When searching, Org-mode will first try an exact match, but
then move on to more and more lenient searches. For example, the link
@samp{[[*My Targets]]} will find any of the following:
@example
** My targets
** TODO my targets are bright
** my 20 targets are
@end example
To insert a link targeting a headline, in-buffer completion can be used.
Just type a star followed by a few optional letters into the buffer and
press @kbd{M-@key{TAB}}. All headlines in the current buffer will be
offered as completions. @xref{Handling links}, for more commands
creating links.
Following a link pushes a mark onto Org-mode's own mark ring. You can
return to the previous position with @kbd{C-c &}. Using this command
several times in direct succession goes back to positions recorded
earlier.

@subsection Radio targets
You can configure Org-mode to link any occurrences of certain target
names in normal text. So without explicitly creating a link, the text
connects to the target radioing its position. Radio targets are
enclosed by triple angular brackets. For example, a target
@samp{<<<My Target>>>} causes each occurrence of @samp{my target} in
normal text to become activated as a link. The Org-mode file is
scanned automatically for radio targets only when the file is first
loaded into Emacs. To update the target list during editing, press
@kbd{C-c C-c} with the cursor on or at a target.

start with a short identifying string followed by a colon. There can be
no space after the colon. The following list shows examples for each
link type.

the link, enclose them in angular brackets.
@node Handling links, Search options, External links, Hyperlinks
@section Handling links
Org-mode provides methods to create a link in the correct syntax, to
insert it into an org-mode file, and to follow the link.
@table @kbd
@kindex C-c l
@cindex storing links
@item C-c l
Store a link to the current location. This is a @emph{global} command
which can be used in any buffer to create a link. The link will be
stored for later insertion into an Org-mode buffer (see below). For
Org-mode files, if there is a @samp{<<target>>} at the cursor, the link
points to the target. Otherwise it points to the current headline. For
VM, RMAIL, WANDERLUST, MH-E, GNUS and BBDB buffers, the link will
indicate the current article/entry. For W3 and W3M buffers, the link
goes to the current URL. For any other files, the link will point to
the file, with a search string (@pxref{Search options}) pointing to the
contents of the current line. If there is an active region, the
selected words will form the basis of the search string. If the
automatically created link is not working correctly or accurately
enough, you can write custom functions to select the search string and
to do the search for particular file types - see @ref{Custom searches}.
The key binding @kbd{C-c l} is only a suggestion - see @ref{Installation}.
@kindex C-c C-l
@cindex link completion
@cindex completion, of links
@cindex inserting links
@item C-c C-l
Insert a link. This prompts for a link to be inserted into the buffer.
You can just type a link, using text for an internal link, or one of the
link type prefixes mentioned in the examples above. Through completion,
all links stored during the current session can be
accessed@footnote{After insertion of a stored link, the link will be
removed from the list of stored links. To keep it in the list later
use, use a triple @kbd{C-u} prefix to @kbd{C-c C-l}, or configure the
option @code{org-keep-stored-link-after-insertion}.}. The link
will be inserted into the buffer, along with a descriptive text. Note
that you don't have to use this command to insert a link. Links in
Org-mode are plain text, and you can type or paste them straight into
the buffer. By using this command, the links are automatically enclosed
in double brackets, and you will be asked for the optional descriptive
text. If the link is a @samp{file:} link and the linked file is located
in the same directory as the current file or a subdirectory of it, the
path of the file will be inserted relative to the current directory.
@kindex C-u C-c C-l
@cindex file name completion
@cindex completion, of file names
@item C-u C-c C-l
When @kbd{C-c C-l} is called with a @kbd{C-u} prefix argument, a link to
a file will be inserted and you may use file name completion to select
the name of the file. The path to the file is inserted relative to the
directory of the current org file, if the linked file is in the current
directory or in a subdirectory of it, or if the path is written relative
to the current directory using @samp{../}. Otherwise an absolute path
is used, if possible with @samp{~/} for your home directory. You can
force an absolute path with two @kbd{C-u} prefixes.
@item C-c C-l @r{with cursor on existing link}
When the cursor is on an existing link, @kbd{C-c C-l} allows you to edit the
link and description parts of the link.
@cindex following links
@kindex C-c C-o
@item C-c C-o
Open link at point. This will launch a web browser for URLs (using
@command{browse-url-at-point}), run vm/mh-e/wanderlust/rmail/gnus/bbdb
for the corresponding links, and execute the command in a shell link.
When the cursor is on an internal link, this commands runs the
corresponding search. When the cursor is on a TAG list in a headline,
it creates the corresponding TAGS view. If the cursor is on a time
stamp, it compiles the agenda for that date. Furthermore, it will visit
text and remote files in @samp{file:} links with Emacs and select a
suitable application for local non-text files. Classification of files
is based on file extension only. See option @code{org-file-apps}. If
you want to override the default application and visit the file with
Emacs, use a @kbd{C-u} prefix.
@kindex mouse-2
@kindex mouse-1
@item mouse-2
@itemx mouse-1
On links, @kbd{mouse-2} will open the link just as @kbd{C-c C-o}
would. Under Emacs 22, also @kbd{mouse-1} will follow a link.
@kindex mouse-3
@item mouse-3
Like @kbd{mouse-2}, but force file links to be opened with Emacs.
@cindex mark ring
@kindex C-c %
@item C-c %
Push the current position onto the mark ring, to be able to return
easily. Commands following an internal link do this automatically.
@cindex links, returning to
@kindex C-c &
@item C-c &
Jump back to a recorded position. A position is recorded by the
commands following internal links, and by @kbd{C-c %}. Using this
command several times in direct succession moves through a ring of
previously recorded positions.
@end table
@node Search options, Custom searches, Handling links, Hyperlinks
@section Search options in file links
@cindex search option in file links
@cindex file links, searching
File links can contain additional information to make Emacs jump to a
particular location in the file when following a link. This can be a
line number or a search option after a double@footnote{For backward
compatibility, line numbers can also follow a single colon.} colon. For
example, when the command @kbd{C-c l} creates a link (@pxref{Handling
links}) to a file, it encodes the words in the current line as a search
string that can be used to find this line back later when following the
link with @kbd{C-c C-o}.
Here is the syntax of the different ways to attach a search to a file
link, together with an explanation:
@example
[[file:~/code/main.c::255]]
[[file:~/xx.org::My Target]]
[[file:~/xx.org::*My Target]]
[[file:~/xx.org::/regexp/]]
@end example
@table @code
@item 255
Jump to line 255.
@item My Target
Search for a link target @samp{<<My Target>>}, or do a text search for
@samp{my target}, similar to the search in internal links, see
@ref{Internal links}. In HTML export (@pxref{HTML export}), such a file
link will become an HTML reference to the corresponding named anchor in
the linked file.
@item *My Target
In an Org-mode file, restrict search to headlines.
@item /regexp/
Do a regular expression search for @code{regexp}. This uses the Emacs
command @code{occur} to list all matches in a separate window. If the
target file is in Org-mode, @code{org-occur} is used to create a
sparse tree with the matches.
@c If the target file is a directory,
@c @code{grep} will be used to search all files in the directory.
@end table
As a degenerate case, a file link with an empty file name can be used
to search the current file. For example, @code{<file:::find me>} does
a search for @samp{find me} in the current file, just as
@samp{[[find me]]} would.
@node Custom searches, Remember, Search options, Hyperlinks
@section Custom Searches
@cindex custom search strings
The default mechanism for creating search strings and for doing the
actual search related to a file link may not work correctly in all
cases. For example, BibTeX database files have many entries like
@samp{year="1993"} which would not result in good search strings,
because the only unique identification for a BibTeX entry is the
citation key.
If you come across such a problem, you can write custom functions to set
the right search string for a particular file type, and to do the search
for the string in the file. Using @code{add-hook}, these functions need
to be added to the hook variables
@code{org-create-file-search-functions} and
@code{org-execute-file-search-functions}. See the docstring for these
variables for more information. Org-mode actually uses this mechanism
for Bib@TeX{} database files, and you can use the corresponding code as
an implementation example. Search for @samp{BibTeX links} in the source
file.
@node Remember, , Custom searches, Hyperlinks
@section Remember
@cindex @file{remember.el}
Another way to create org entries with links to other files is through
the @emph{Remember} package by John Wiegley. @emph{Remember} lets you
store quick notes with little interruption of your work flow. See
@uref{http://www.emacswiki.org/cgi-bin/wiki/RememberMode} for more
information. The notes produced by @emph{Remember} can be stored in
different ways, and Org-mode files are a good target. Org-mode allows
you to file away notes either to a default file, or directly to the correct
location in your Org-mode outline tree. The following customization
will tell @emph{Remember} to use org files as target, and to create
annotations compatible with Org-mode links.
@example
(setq org-directory "~/path/to/my/orgfiles/")
(setq org-default-notes-file "~/.notes")
(setq remember-annotation-functions '(org-remember-annotation))
(setq remember-handler-functions '(org-remember-handler))
(add-hook 'remember-mode-hook 'org-remember-apply-template)
@end example
@cindex templates, for remember
In combination with Org-mode, you can use templates to generate
different types of remember notes. For example, if you would like to
use one template to create general TODO entries, and another one for
journal entries, you could use:
@example
(setq org-remember-templates
'((?t "* TODO %?\n %i\n %a" "~/org/TODO.org")
(?j "* %U %?\n\n %i\n %a" "~/org/JOURNAL.org")))
@end example
@noindent In these entries, the character specifies how to select the
template, the first string specifies the template, and the (optional)
second string specifies a default file (overruling
@code{org-default-notes-file}) as a target for this note.
When you call @kbd{M-x remember} to remember something, org will prompt
for a key to select the template and then prepare the buffer like
@example
* TODO
<file:link to where you called remember>
@end example
@noindent or
@example
* [2006-03-21 Tue 15:37]
<file:link to where you called remember>
@end example
@noindent See the variable @code{org-remember-templates} for more details.
When you are finished composing a note with remember, you have to press
@kbd{C-c C-c} to file the note away. The handler first prompts for a
target file - if you press @key{RET}, the value of
@code{org-default-notes-file} is used. Then the command offers the
headings tree of the selected file. You can either immediately press
@key{RET} to get the note appended to the file. Or you can use vertical
cursor motion (@key{up} and @key{down}) and visibility cycling
(@key{TAB}) to find a better place. Pressing @key{RET} or @key{left} or
@key{right} leads to the following result.
@multitable @columnfractions 0.2 0.1 0.7
@item @b{Cursor position} @tab @b{Key} @tab @b{Note gets inserted}
@item buffer-start @tab @key{RET} @tab as level 2 heading at end of file
@item on headline @tab @key{RET} @tab as sublevel of the heading at cursor
@item @tab @key{left} @tab as same level, before current heading
@item @tab @key{right} @tab as same level, after current heading
@item not on headline @tab @key{RET}
@tab at cursor position, level taken from context.
Or use prefix arg to specify level manually.
@end multitable
So a fast way to store the note is to press @kbd{C-c C-c @key{RET}
@key{RET}} to append it to the default file. Even shorter would be
@kbd{C-u C-c C-c}, which does the same without even showing the tree.
But with little extra effort, you can push it directly to the correct
location.
Before inserting the text into a tree, the function ensures that the
text has a headline, i.e. a first line that starts with a @samp{*}.
If not, a headline is constructed from the current date and some
additional data. If the variable @code{org-adapt-indentation} is
non-nil, the entire text is also indented so that it starts in the
same column as the headline (after the asterisks).

@chapter TODO items
@cindex TODO items
Org-mode does not maintain TODO lists as a separate document. TODO
items are an integral part of the notes file, because TODO items
usually come up while taking notes! With Org-mode, you simply mark
any entry in a tree as being a TODO item. In this way, the
information is not duplicated, and the entire context from which the
item emerged is always present when you check.
Of course, this technique causes TODO items to be scattered throughout
your file. Org-mode provides methods to give you an overview over all
things you have to do.

Rotate the TODO state of the current item between
@example

The same rotation can also be done ``remotely'' from the timeline and
agenda buffers with the @kbd{t} command key (@pxref{Agenda commands}).
@kindex S-@key{right}
@kindex S-@key{left}
@item S-@key{right}
@itemx S-@key{left}
Select the following/preceding TODO state, similar to cycling. Mostly
useful if more than two TODO states are possible (@pxref{TODO extensions}).
@kindex C-c C-v
@cindex sparse tree, for TODO
@item C-c C-v
View TODO items in a @emph{sparse tree} (@pxref{Sparse trees}). Folds
the entire buffer, but shows all TODO items and the headings hierarchy
above them. With prefix arg, show also the DONE entries. With
numerical prefix N, show the tree for the Nth keyword in the variable
@code{org-todo-keywords}.
@kindex C-c a t
@item C-c a t
Show the global TODO list. This collects the TODO items from all
agenda files (@pxref{Agenda views}) into a single buffer. The buffer is in
@code{agenda-mode}, so there are commands to examine and manipulate
the TODO entries directly from that buffer (@pxref{Agenda commands}).

types of action items. For example, you might want to indicate that
items are for ``work'' or ``home''. If you are into David Allen's
@emph{Getting Things DONE}, you might want to use todo types
@samp{NEXTACTION}, @samp{WAITING}, @samp{MAYBE}. Or, when you work
with several people on a single project, you might want to assign
action items directly to persons, by using their names as TODO
keywords. This would be set up like this:
@lisp
(setq org-todo-keywords '("Fred" "Sara" "Lucy" "Mike" "DONE")
org-todo-interpretation 'type)
@end lisp
In this case, different keywords do not indicate a sequence, but
rather different types. So it is normally not useful to change from
one type to another. Therefore, in this case the behavior of the
command @kbd{C-c C-t} is changed slightly@footnote{This is also true
for the @kbd{t} command in the timeline and agenda buffers.}. When
used several times in succession, it will still cycle through all
names. But when you return to the item after some time and execute
@kbd{C-c C-t} again, it will switch from each name directly to DONE.
Use prefix arguments or completion to quickly select a specific name.
You can also review the items of a specific TODO type in a sparse tree
by using a numeric prefix to @kbd{C-c C-v}. For example, to see all
things Lucy has to do, you would use @kbd{C-3 C-c C-v}. To collect
Lucy's items from all agenda files into a single buffer, you
would use the prefix arg as well when creating the global todo list:
@kbd{C-3 C-c t}.
@node Per file keywords, , TODO types, TODO extensions
@subsection Setting up TODO keywords for individual files
@cindex keyword options
@cindex per file keywords
It can be very useful to use different aspects of the TODO mechanism
in different files, which is not possible with the global settings
described above. For file-local settings, you need to add special
lines to the file which set the keywords and interpretation for that
file only. For example, to set one of the two examples discussed
above, you need one of the following lines, starting in column zero
anywhere in the file:
@example
#+SEQ_TODO: TODO FEEDBACK VERIFY DONE
#+TYP_TODO: Fred Sara Lucy Mike DONE
@end example
@cindex Completion, of option keywords
@kindex M-@key{TAB}
@noindent To make sure you are using the correct keyword, type
@samp{#+} into the buffer and then use @kbd{M-@key{TAB}} completion.
@cindex DONE, final TODO keyword
Remember that the last keyword must always mean that the item is DONE
(although you may use a different word). Also note that in each file,
only one of the two aspects of TODO keywords can be used. After
changing one of these lines, use @kbd{C-c C-c} with the cursor still
in the line to make the changes known to Org-mode@footnote{Org-mode
parses these lines only when Org-mode is activated after visiting a
file. @kbd{C-c C-c} with the cursor in a line starting with @samp{#+}
is simply restarting Org-mode, making sure that these changes will be
respected.}.
If you want to use very many keywords, for example when working with a
large group of people, you may split the names over several lines:
@example
#+TYP_TODO: Fred Sara Lucy Mike
#+TYP_TODO: Luis George Jules Jessica
#+TYP_TODO: Kim Arnold Peter
#+TYP_TODO: DONE
@end example
@node Priorities, , TODO extensions, TODO items
@section Priorities
@cindex priorities
If you use Org-mode extensively to organize your work, you may end up
with a number of TODO entries so large that you'd like to prioritize
them. This can be done by placing a @emph{priority cookie} into the
headline, like this
@example
*** TODO [#A] Write letter to Sam Fortune
@end example
@noindent
With its standard setup, Org-mode supports priorities @samp{A},
@samp{B}, and @samp{C}. @samp{A} is the highest priority. An entry
without a cookie is treated as priority @samp{B}. Priorities make a
difference only in the agenda (@pxref{Weekly/Daily agenda}).
@table @kbd
@kindex @kbd{C-c ,}
@item @kbd{C-c ,}
Set the priority of the current headline. The command prompts for a
priority character @samp{A}, @samp{B} or @samp{C}. When you press
@key{SPC} instead, the priority cookie is removed from the headline.
The priorities can also be changed ``remotely'' from the timeline and
agenda buffer with the @kbd{,} command (@pxref{Agenda commands}).
@kindex S-@key{up}
@kindex S-@key{down}
@item S-@key{up}
@itemx S-@key{down}
Increase/decrease priority of current headline. Note that these keys
are also used to modify time stamps (@pxref{Creating timestamps}).
Furthermore, these keys are also used by CUA-mode (@pxref{Conflicts}).

A time stamp is a specification of a date (possibly with time) in a
special format, either @samp{<2003-09-16 Tue>} or @samp{<2003-09-16
Tue 09:39>}. A time stamp can appear anywhere in the headline or body
of an org-tree entry. Its presence allows entries to be shown on specific
dates in the agenda (@pxref{Weekly/Daily agenda}). We distinguish:
@table @var
@item Plain time stamp
@cindex timestamp
A simple time stamp just assigns a date/time to an item. This is just
like writing down an appointment in a paper agenda, or like writing down
an event in a diary, when you want to take note of when something
happened. In the timeline and agenda displays, the headline of an entry
associated with a plain time stamp will be shown exactly on that date.
@item Time stamp range
@cindex timerange
Two time stamps connected by @samp{--} denote a time range. The
headline will be shown on the first and last day of the range, and on
any dates that are displayed and fall in the range. Here is an
example:
@example
** Meeting in Amsterdam
<2004-08-23 Mon>--<2004-08-26 Thu>
@end example
@item Time stamp with SCHEDULED keyword
@cindex SCHEDULED keyword
If a time stamp is preceded by the word @samp{SCHEDULED:}, it means you
are planning to start working on that task on the given date. So this is
not about recording an event, but about planning your work. The
headline will be listed under the given date. In addition, a reminder
that the scheduled date has passed will be present in the compilation
for @emph{today}, until the entry is marked DONE. I.e., the task will
automatically be forwarded until completed.
@example
*** TODO Call Trillian for a date on New Years Eve.
SCHEDULED: <2004-12-25 Sat>
@end example
@item Time stamp with DEADLINE keyword
@cindex DEADLINE keyword
If a time stamp is preceded by the word @samp{DEADLINE:}, the task
(most likely a TODO item) is supposed to be finished on that date, and
it will be listed then. In addition, the compilation for @emph{today}
will carry a warning about the approaching or missed deadline,
starting @code{org-deadline-warning-days} before the due date, and
continuing until the entry is marked DONE. An example:
@example
*** TODO write article about the Earth for the Guide
The editor in charge is <bbdb:Ford Prefect>
DEADLINE: <2004-02-29 Sun>
@end example
@item Time stamp with CLOSED keyword
@cindex CLOSED keyword
When @code{org-log-done} is non-nil, Org-mode will automatically insert
a special time stamp each time a TODO entry is marked done
(@pxref{Progress logging}). This time stamp is enclosed in square
brackets instead of angular brackets.
@item Time range with CLOCK keyword
@cindex CLOCK keyword
When using the clock to time the work that is being done on specific
items, time ranges preceded by the CLOCK keyword are inserted
automatically into the file. The time stamps are enclosed in square
brackets instead of angular brackets. @xref{Clocking work time}.

@subsection Closing items
If you want to keep track of @emph{when} a certain TODO item was

@lisp
(setq org-log-done t)
@end lisp
@noindent
Then each time you turn a TODO entry into DONE using either @kbd{C-c
C-t} in the Org-mode buffer or @kbd{t} in the agenda buffer, a line
@samp{CLOSED: [timestamp]} will be inserted just after the headline.
If you turn the entry back into a TODO item again through further
state cycling, that line will be removed again. In the timeline
(@pxref{Timeline}) and in the agenda (@pxref{Weekly/Daily agenda}),
you can then use the @kbd{l} key to display the TODO items closed on
each day, giving you an overview of what has been done on a day.
@node Clocking work time, , Closing items, Progress logging
@subsection Clocking work time
Org-mode allows you to clock the time you spent on specific tasks in a
project. When you start working on an item, you can start the clock.
When you stop working on that task, or when you mark the task done, the
clock is stopped and the corresponding time interval is recorded. It
also computes the total time spent on each subtree of a project.
@table @kbd
@kindex C-c C-x C-i
@item C-c C-x C-i
Start the clock on the current item (clock-in). This inserts the CLOCK
keyword together with a timestamp.
@kindex C-c C-x C-o
@item C-c C-x C-o
Stop the clock (clock-out). The inserts another timestamp at the same
location where the clock was last started. It also directly computes
the resulting time in inserts it after the time range as @samp{=>
HH:MM}.
@kindex C-c C-y
@item C-c C-y
Recompute the time interval after changing one of the time stamps. This
is only necessary if you edit the time stamps directly. If you change
them with @kbd{S-@key{cursor}} keys, the update is automatic.
@kindex C-c C-t
@item C-c C-t
Changing the TODO state of an item to DONE automatically stops the clock
if it is running in this same item.
@kindex C-c C-x C-x
@item C-c C-x C-x
Cancel the current clock. This is useful if a clock was started by
mistake, or if you ended up working on something else.
@kindex C-c C-x C-d
@item C-c C-x C-d
Display time summaries for each subtree in the current buffer. This
puts overlays at the end of each headline, showing the total time
recorded under that heading, including the time of any subheadings. You
can use visibility cycling to study the tree, but the overlays disappear
automatically when the buffer is changed.
@kindex C-c C-x C-r
@item C-c C-x C-r
Insert a dynamic block (@pxref{Dynamic blocks}) containing a clock
report as an org-mode table into the current file.
@example
#+BEGIN: clocktable :maxlevel 2 :emphasize nil
#+END: clocktable
@end example
@noindent
If such a block already exists, its content is replaced by the new
table. The @samp{BEGIN} line can specify options:
@example
:maxlevels @r{Maximum level depth to which times are listed in the table.}
:emphasize @r{When @code{t}, emphasize level one and level two items}
:block @r{The time block to consider. This block is specified relative}
@r{to the current time and may be any of these keywords:}
@r{@code{today}, @code{yesterday}, @code{thisweek}, @code{lastweek},}
@r{@code{thismonth}, @code{lastmonth}, @code{thisyear}, or @code{lastyear}}.
:tstart @r{A time string specifying when to start considering times}
:tend @r{A time string specifying when to stop considering times}
@end example
So to get a clock summary for the current day, you could write
@example
#+BEGIN: clocktable :maxlevel 2 :block today
#+END: clocktable
@end example
and to use a specific time range you could write@footnote{Note that all
parameters must be specified in a single line - the line is broken here
only to fit it onto the manual.}
@example
#+BEGIN: clocktable :tstart "<2006-08-10 Thu 10:00>"
:tend "<2006-08-10 Thu 12:00>"
#+END: clocktable
@end example
@kindex C-u C-c C-x C-u
@item C-u C-c C-x C-u
Update all dynamic blocks (@pxref{Dynamic blocks}). This is useful if
you have several clocktable blocks in a buffer.
@end table
The @kbd{l} key may be used in the timeline (@pxref{Timeline}) and in

If you wish to implement a system of labels and contexts for
cross-correlating information, an excellent way is to assign @i{tags} to
headlines. Org-mode has extensive support for using tags.
Every headline can contain a list of tags, at the end of the headline.
Tags are normal words containing letters, numbers, @samp{_}, and
@samp{@@}. Tags must be preceded and followed by a single colon; like
@samp{:WORK:}. Several tags can be specified like @samp{:WORK:URGENT:}.

@end menu
@node Tag inheritance, Setting tags, Tags, Tags
@section Tag inheritance
@cindex inheritance, of tags
@i{Tags} make use of the hierarchical structure of outline trees. If a
heading has a certain tag, all subheadings will inherit the tag as
well. For example, in the list
@example
* Meeting with the French group :WORK:
** Summary by Frank :BOSS:NOTES:
*** TODO Prepare slides for him :ACTION:
@end example
@noindent
the final heading will have the tags @samp{:WORK:}, @samp{:BOSS:},
@samp{:NOTES:}, and @samp{:ACTION:}. When executing tag searches and
Org-mode finds that a certain headline matches the search criterion, it
will not check any sublevel headline, assuming that these likely also
match, and that the list of matches can become very long. This may
not be what you want, however, and you can influence inheritance and
searching using the variables @code{org-use-tag-inheritance} and
@code{org-tags-match-list-sublevels}.
@node Setting tags, Tag searches, Tag inheritance, Tags
@section Setting tags
@cindex setting tags
@kindex M-@key{TAB}
Tags can simply be typed into the buffer at the end of a headline.
After a colon, @kbd{M-@key{TAB}} offers completion on tags. There is
also a special command for inserting tags:
@table @kbd
@kindex C-c C-c
@item C-c C-c
@cindex completion, of tags
Enter new tags for the current headline. Org-mode will either offer
completion or a special single-key interface for setting tags, see
below. After pressing @key{RET}, the tags will be inserted and aligned
to @code{org-tags-column}. When called with a @kbd{C-u} prefix, all
tags in the current buffer will be aligned to that column, just to make
things look nice. TAGS are automatically realigned after promotion,
demotion, and TODO state changes (@pxref{TODO basics}).
@end table
Org will support tag insertion based on a @emph{list of tags}. By
default this list is constructed dynamically, containing all tags
currently used in the buffer. You may also globally specify a hard list
of tags with the variable @code{org-tag-alist}. Finally you can set
the allowed tags for a given file with lines like
@example
#+TAGS: @@WORK @@HOME @@TENNISCLUB
#+TAGS: Laptop Car PC Sailboat
@end example
The default support method is minibuffer completion. However, Org-mode
also implements a much better method: @emph{fast tag selection}. This
method allows to select and deselect tags with a single key per tag. To
function efficiently, you should assign unique keys to all tags. This
can be done globally with
@lisp
(setq org-tag-alist '(("@@WORK" . ?w) ("@@HOME" . ?h) ("Laptop" . ?l)))
@end lisp
@noindent or on a per-file basis with
@example
#+TAGS: @@WORK(w) @@HOME(h) @@TENNISCLUB(t) Laptop(l) PC(p)
@end example
@noindent
You can also group together tags that are mutually exclusive. With
curly braces@footnote{In @code{org-mode-alist} use
@code{'(:startgroup)} and @code{'(:endgroup)}, respectively. Several
groups are allowed.}
@example
#+TAGS: @{ @@WORK(w) @@HOME(h) @@TENNISCLUB(t) @} Laptop(l) PC(p)
@end example
@noindent you indicate that at most one of @samp{@@WORK}, @samp{@@HOME},
and @samp{@@TENNISCLUB} should be selected.
@noindent Don't forget to press @kbd{C-c C-c} with the cursor in one of
these lines to activate any changes.
If at least one tag has a selection key, pressing @kbd{C-c C-c} will
automatically present you with a special interface, listing inherited
tags, the tags of the current headline, and a list of all legal tags
with corresponding keys@footnote{Keys will automatically assigned to
tags which have no configured keys.}. Pressing keys for the tags will
add or remove them from the list of tags in the current line. Selecting
a tag in a group of mutually exclusive tags will turn off any other tags
from that group. @key{SPC} clears all tags for this line, @kbd{RET}
accepts the modified set, and @kbd{C-g} aborts without installing
changes. This method lets you assign tags to a headline with very few
keys. With the above setup, you could clear the current tags and set
@samp{@@HOME}, @samp{Laptop} and @samp{PC} tags with just the following
keys: @kbd{C-c C-c @key{SPC} h l p @key{RET}}. Switching from
@samp{@@HOME} to @samp{@@WORK} would be done with @kbd{C-c C-c w
@key{RET}}.
What if you have globally defined your preferred set of tags using the
variable @code{org-tag-alist}, but would like to use a dynamic tag list
in a specific file? Just add an empty TAGS option line to that file:
@example
#+TAGS:
@end example
@node Tag searches, , Setting tags, Tags

@cindex tag searches
Once a tags system has been set up, it can be used to collect related
information into special lists.

@item C-c a M
Create a global list of tag matches from all agenda files, but check
only TODO items and force checking subitems (see variable

@end table
A @i{tags} search string can use Boolean operators @samp{&} for AND and
@samp{|} for OR. @samp{&} binds more strongly than @samp{|}.
Parenthesis are currently not implemented. A tag may also be preceded
by @samp{-}, to select against it, and @samp{+} is syntactic sugar for
positive selection. The AND operator @samp{&} is optional when @samp{+}
or @samp{-} is present. For example, @samp{+WORK-BOSS} would select all
headlines that are tagged @samp{:WORK:}, but discard those also tagged
@samp{:BOSS:}. The search string @samp{WORK|LAPTOP} selects all lines
tagged @samp{:WORK:} or @samp{:LAPTOP:}. The string
@samp{WORK|LAPTOP&NIGHT} requires that the @samp{:LAPTOP:} lines are
also tagged @samp{NIGHT}.
@node Agenda views, Embedded LaTeX, Tags, Top
@chapter Agenda Views
@cindex agenda views
Due to the way Org-mode works, TODO items, time-stamped items, and
tagged headlines can be scattered throughout a file or even a number of
files. To get an overview over open action items, or over events that
are important for a particular date, this information must be collected,
sorted and displayed in an organized way.
Org-mode can select items based on various criteria, and display them
in a separate buffer. Three different views are provided:
@itemize @bullet
@item
an @emph{agenda} that is like a calendar and shows information
for specific dates
@item
a @emph{TODO list} that covers all unfinished
action items, and
@item
a @emph{tags view} that shows information based on
the tags associated with headlines in the outline tree.
@end itemize

The extracted information is displayed in a special @emph{agenda

following we will assume that @kbd{C-c a} is indeed how the dispatcher
is accessed and list keyboard access to commands accordingly. After
pressing @kbd{C-c a}, an additional letter is required to execute a

@table @kbd

@item t / T
Create a list of all TODO items (@pxref{Global TODO list}).
@item m / M

@end table
You can also define custom commands that will be accessible through
the dispatcher, just like the default commands. Custom commands are
global searches for tags and specific TODO keywords, or a variety of
sparse tree creating commands (@pxref{Sparse trees}). As sparse trees
are only defined for a single org-mode file, these latter commands act
on the current buffer instead of the list of agenda files.
@kindex C-c a C
Custom commands are configured in the variable

with Emacs Lisp in @file{.emacs}. For example:
@lisp
(setq org-agenda-custom-commands
'(("w" todo "WAITING")
("u" tags "+BOSS-URGENT")
("U" tags-tree "+BOSS-URGENT")
("f" occur-tree "\\<FIXME\\>")))
@end lisp
@noindent will define @kbd{C-c a w} as a global search for
TODO entries with @samp{WAITING} as the TODO keyword, @kbd{C-c a u} as a
global tags search for headlines marked @samp{:BOSS:} but not
@samp{:URGENT:}, @kbd{C-c a U} to do the same search but only in the
current buffer and display the result as a sparse tree, and @kbd{C-c a
f} to create a sparse tree with all entries containing the word
@samp{FIXME}. For more information, look at the documentation string
of the variable @code{org-agenda-custom-commands}.
@node Weekly/Daily agenda, Global TODO list, Agenda dispatcher, Agenda views
@section The weekly/daily agenda
@cindex agenda
The purpose of the weekly/daily @emph{agenda} is to act like a page of
a paper agenda, showing all the tasks for the current week or day.
@table @kbd
@cindex org-agenda, command
@kindex C-c a a
@item C-c a a
Compile an agenda for the current week from a list of org files. The
agenda shows the entries for each day. With a @kbd{C-u} prefix (or
when the variable @code{org-agenda-include-all-todo} is @code{t}), all
unfinished TODO items (including those without a date) are also listed at
the beginning of the buffer, before the first date.@*
@end table
Remote editing from the agenda buffer means, for example, that you can
change the dates of deadlines and appointments from the agenda buffer.
The commands available in the Agenda buffer are listed in @ref{Agenda
commands}.
@menu
* Categories:: Not all tasks are equal
* Time-of-day specifications:: How the agenda knows the time
* Calendar/Diary integration:: Integrating Anniversaries and more
* Sorting of agenda items:: The order of things
@end menu
@node Categories, Time-of-day specifications, Weekly/Daily agenda, Weekly/Daily agenda
@subsection Categories
@cindex category
In the agenda buffer, each entry is preceded by a @emph{category},
which is derived from the file name. The category can also be set
with a special line anywhere in the buffer, looking like this:
@example
#+CATEGORY: Thesis
@end example
If there are several such lines in a file, each specifies the category
for the text below it (but the first category also applies to any text
before the first CATEGORY line). The display in the agenda buffer looks
best if the category is not longer than 10 characters.
@node Time-of-day specifications, Calendar/Diary integration, Categories, Weekly/Daily agenda
@subsection Time-of-Day Specifications
Org-mode checks each agenda item for a time-of-day specification. The
time can be part of the time stamp that triggered inclusion into the
agenda, for example as in @w{@samp{<2005-05-10 Tue 19:00>}}. Time
ranges can be specified with two time stamps, like
@c
@w{@samp{<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>}}.
In the headline of the entry itself, a time(range) may also appear as
plain text (like @samp{12:45} or a @samp{8:30-1pm}. If the agenda
integrates the Emacs diary (@pxref{Calendar/Diary integration}), time
specifications in diary entries are recognized as well.
For agenda display, Org-mode extracts the time and displays it in a
standard 24 hour format as part of the prefix. The example times in
the previous paragraphs would end up in the agenda like this:
@example
8:30-13:00 Arthur Dent lies in front of the bulldozer
12:45...... Ford Prefect arrives and takes Arthur to the pub
19:00...... The Vogon reads his poem
20:30-22:15 Marwin escorts the Hitchhikers to the bridge
@end example
If the agenda is in single-day mode, or for the display of today, the
timed entries are embedded in a time grid, like
@example
8:00...... ------------------
8:30-13:00 Arthur Dent lies in front of the bulldozer
10:00...... ------------------
12:00...... ------------------
12:45...... Ford Prefect arrives and takes Arthur to the pub
14:00...... ------------------
16:00...... ------------------
18:00...... ------------------
19:00...... The Vogon reads his poem
20:00...... ------------------
20:30-22:15 Marwin escorts the Hitchhikers to the bridge
@end example
The time grid can be turned on and off with the variable
@code{org-agenda-use-time-grid}, and can be configured with
@code{org-agenda-time-grid}.
@node Calendar/Diary integration, Sorting of agenda items, Time-of-day specifications, Weekly/Daily agenda
@subsection Calendar/Diary integration
@cindex calendar integration
@cindex diary integration
Emacs contains the calendar and diary by Edward M. Reingold. The
calendar displays a three-month calendar with holidays from different
countries and cultures. The diary allows you to keep track of
anniversaries, lunar phases, sunrise/set, recurrent appointments
(weekly, monthly) and more. In this way, it is quite complementary to
Org-mode. It can be very useful to combine output from Org-mode with
the diary.
In order to include entries from the Emacs diary into Org-mode's
agenda, you only need to customize the variable
@lisp
(setq org-agenda-include-diary t)
@end lisp
@noindent After that, everything will happen automatically. All diary
entries including holidays, anniversaries etc will be included in the
agenda buffer created by Org-mode. @key{SPC}, @key{TAB}, and
@key{RET} can be used from the agenda buffer to jump to the diary
file in order to edit existing diary entries. The @kbd{i} command to
insert new entries for the current date works in the agenda buffer, as
well as the commands @kbd{S}, @kbd{M}, and @kbd{C} to display
Sunrise/Sunset times, show lunar phases and to convert to other
calendars, respectively. @kbd{c} can be used to switch back and forth
between calendar and agenda.
@node Sorting of agenda items, , Calendar/Diary integration, Weekly/Daily agenda
@subsection Sorting of agenda items
@cindex sorting, of agenda items
@cindex priorities, of agenda items
The entries for each day are sorted. The default order is to first
collect all items containing an explicit time-of-day specification.
These entries will be shown at the beginning of the list, as a
@emph{schedule} for the day. After that, items remain grouped in
categories, in the sequence given by @code{org-agenda-files}. Within
each category, items are sorted by priority (@pxref{Priorities}).
The priority is a numerical quantity composed of the base priority
(2000 for priority @samp{A}, 1000 for @samp{B}, and 0 for @samp{C}),
plus additional increments for overdue scheduled or deadline items.
Sorting can be customized using the variable
@code{org-agenda-sorting-strategy}.
@node Global TODO list, Matching headline tags, Weekly/Daily agenda, Agenda views
@section The global TODO list
@cindex global TODO list
@cindex TODO list, global
The global TODO list contains all unfinished TODO items, formatted and
collected into a single place.
@table @kbd
@kindex C-c a t
@item C-c a t
Show the global TODO list. This collects the TODO items from all
agenda files (@pxref{Agenda views}) into a single buffer. The buffer is in
@code{agenda-mode}, so there are commands to examine and manipulate
the TODO entries directly from that buffer (@pxref{Agenda commands}).
@kindex C-c a T
@item C-c a T
Like the above, but allows selection of a specific TODO keyword. You can
also do this by specifying a prefix argument to @kbd{C-c a t}. With a
@kbd{C-u} prefix you are prompted for a keyword. With a numeric
prefix, the Nth keyword in @code{org-todo-keywords} is selected.
@kindex r
The @kbd{r} key in the agenda buffer regenerates it, and you can give
a prefix argument to this command to change the selected TODO keyword,
for example @kbd{3 r}. If you often need a search for a specific
keyword, define a custom command for it (@pxref{Agenda dispatcher}).
@end table
Remote editing of TODO items means that you can change the state of a
TODO entry with a single key press. The commands available in the
TODO list are described in @ref{Agenda commands}.
Nomally the global todo list simply shows all headlines with TODO
keywords. This list can become very long. There are two ways to keep
it more compact:
@itemize @minus
@item
Some people view a TODO item that has been @emph{scheduled} for
execution (@pxref{Time stamps}) as no longer @emph{open}. Configure the
variable @code{org-agenda-todo-ignore-scheduled} to exclude scheduled
items from the global TODO list.
@item
TODO items may have sublevels to break up the task into subtasks. In
such cases it may be enough to list only the highest level TODO headline
and omit the sublevels from the global list. Configure the variable
@code{org-agenda-todo-list-sublevels} to get this behavior.
@end itemize

define a custom command for it (@pxref{Agenda dispatcher}).
@kindex C-c a M

@cindex commands, in agenda buffer
Entries in the agenda buffer are linked back to the org file or diary
file where they originate. You are not allowed to edit the agenda
buffer itself, but commands are provided to show and jump to the
original entry location, and to edit the org-files ``remotely'' from
the agenda buffer. In this way, all information is stored only once,
removing the risk that your agenda and note files may diverge.
Some commands can be executed with mouse clicks on agenda lines. For
the other commands, the cursor needs to be in the desired line.
@table @kbd

@kindex mouse-2
@kindex mouse-1
@kindex @key{TAB}
@item mouse-2
@itemx mouse-1
@itemx @key{TAB}
Go to the original location of the item in another window. Under Emacs
22, @kbd{mouse-1} will also works for this.
@kindex @key{RET}
@itemx @key{RET}
Go to the original location of the item and delete other windows.
@kindex f
@item f
Toggle Follow mode. In Follow mode, as you move the cursor through
the agenda buffer, the other window always shows the corresponding
location in the org file. The initial setting for this mode in new
agenda buffers can be set with the variable
@code{org-agenda-start-with-follow-mode}.
@kindex l
@item l
Toggle Logbook mode. In Logbook mode, entries that where marked DONE while
logging was on (variable @code{org-log-done}) are shown in the agenda,
as are entries that have been clocked on that day.
@tsubheading{Change display}
@kindex o

@kindex g
@item g
Toggle the time grid on and off. See also the variables
@code{org-agenda-use-time-grid} and @code{org-agenda-time-grid}.
@kindex r
@item r
Recreate the agenda buffer, for example to reflect the changes
after modification of the time stamps of items with S-@key{left} and
S-@key{right}. When the buffer is the global todo list, a prefix
argument is interpreted to create a selective list for a specific TODO
keyword.
@kindex s
@item s

inheritance, this may be more than the tags listed in the line itself.
@kindex :
@item :
Set tags for the current headline.
@kindex a
@item a
Toggle the ARCHIVE tag for the current headline.
@kindex ,

the original buffer, but the agenda is not resorted. Use the @kbd{r}
key for this.
@kindex -
@kindex S-@key{down}
@item -
@itemx S-@key{down}
Decrease the priority of the current item.
@kindex C-c C-s
@item C-c C-s
Schedule this item
@kindex C-c C-d
@item C-c C-d
Set a deadline for this item.
@kindex S-@key{right}
@item S-@key{right}
Change the time stamp associated with the current line by one day into
the future. With prefix argument, change it by that many days. For
example, @kbd{3 6 5 S-@key{right}} will change it by a year. The
stamp is changed in the original org file, but the change is not
directly reflected in the agenda buffer. Use the
@kbd{r} key to update the buffer.
@kindex S-@key{left}
@item S-@key{left}
Change the time stamp associated with the current line by one day

@chapter Embedded LaTeX
@cindex @TeX{} interpretation
@cindex La@TeX{} interpretation
Plain ASCII is normally sufficient for almost all note taking. One
exception, however, are scientific notes which need to be able to
contain mathematical symbols and the occasional formula.
La@TeX{}@footnote{La@TeX{} is a macro system based on Donald E. Knuth's
@TeX{} system. Many of the features described here as ``La@TeX{}'' are
really from @TeX{}, but for simplicity I am blurring this distinction.}
is widely used to typeset scientific documents. Org-mode supports
embedding La@TeX{} code into its files, because many academics are used
to read La@TeX{} source code, and because it can be readily processed
into images for HTML production.
It is not necessary to mark La@TeX{} macros and code in any special way.
If you observe a few conventions, Org-mode knows how to find it and what
to do with it.
@menu
* Math symbols:: TeX macros for symbols and Greek letters
* Subscripts and Superscripts:: Simple syntax for raising/lowering text
* LaTeX fragments:: Complex formulas made easy
* Processing LaTeX fragments:: Previewing LaTeX processing
* CDLaTeX mode:: Speed up entering of formulas
@end menu
@node Math symbols, Subscripts and Superscripts, Embedded LaTeX, Embedded LaTeX
@section Math symbols
You can use La@TeX{} macros to insert special symbols like @samp{\alpha}
to indicate the Greek letter, or @samp{\to} to indicate an arrow.
Completion for these macros is available, just type @samp{\} and maybe a
few letters, and press @kbd{M-@key{TAB}} to see possible completions.
Unlike La@TeX{} code, Org-mode allows these macros to be present
without surrounding math delimiters, for example:
@example
Angles are written as Greek letters \alpha, \beta and \gamma.
@end example
During HTML export (@pxref{HTML export}), these symbols are translated
into the proper syntax for HTML, for the above examples this is
@samp{&alpha;} and @samp{&rarr;}, respectively.
@node Subscripts and Superscripts, LaTeX fragments, Math symbols, Embedded LaTeX
@section Subscripts and Superscripts
Just like in La@TeX{}, @samp{^} and @samp{_} are used to indicate super-
and subscripts. Again, these can be used without embedding them in
math-mode delimiters. To increase the readability of ASCII text, it is
not necessary (but OK) to surround multi-character sub- and superscripts
with curly braces. For example
@example
The mass if the sun is M_sun = 1.989 x 10^30 kg. The radius of
the sun is R_@{sun@} = 6.96 x 10^8 m.
@end example
To avoid interpretation as raised or lowered text, you can quote
@samp{^} and @samp{_} with a backslash: @samp{\_} and @samp{\^}.
During HTML export (@pxref{HTML export}), subscript and superscripts
are surrounded with @code{<sub>} and @code{<sup>} tags, respectively.
@node LaTeX fragments, Processing LaTeX fragments, Subscripts and Superscripts, Embedded LaTeX
@section LaTeX fragments
With symbols, sub- and superscripts, HTML is pretty much at its end when
it comes to representing mathematical formulas. More complex
expressions need a dedicated formula processor. To this end, Org-mode
can contain arbitrary La@TeX{} fragments. It provides commands to
preview the typeset result of these fragments, and upon export to HTML,
all fragments will be converted to images and inlined into the HTML
document. For this to work you need to be on a system with a working
La@TeX{} installation. You also need the @file{dvipng} program,
available at @url{http://sourceforge.net/projects/dvipng/}.
La@TeX{} fragments don't need any special marking at all. The following
snippets will be identified as LaTeX source code:
@itemize @bullet
@item
Environments of any kind. The only requirement is that the
@code{\begin} statement appears on a new line, preceded by only
whitespace.
@item
Text within the usual La@TeX{} math delimiters. To avoid conflicts with
currency specifications, single @samp{$} characters are only recognized
as math delimiters if the enclosed text contains at most two line breaks,
is directly attached to the @samp{$} characters with no whitespace in
between, and if the closing @samp{$} is followed by whitespace or
punctuation. For the other delimiters, there is no such restriction, so
when in doubt, use @samp{\(...\)} as inline math delimiters.
@end itemize
@noindent For example:
@example
\begin@{equation@} % arbitrary environments,
x=\sqrt@{b@} % even tables, figures
\end@{equation@} % etc
If $a^2=b$ and \( b=2 \), then the solution must be
either $$ a=+\sqrt@{2@} $$ or \[ a=-\sqrt@{2@} \].
@end example
@noindent
If you need any of the delimiter ASCII sequences for other purposes, you
can configure the option @code{org-format-latex-options} to deselect the
ones you do not wish to have interpreted by the La@TeX{} converter.
@node Processing LaTeX fragments, CDLaTeX mode, LaTeX fragments, Embedded LaTeX
@section Processing LaTeX fragments
La@TeX{} fragments can be processed to produce a preview images of the
typeset expressions:
@table @kbd
@kindex C-c C-x C-l
@item C-c C-x C-l
Produce a preview image of the La@TeX{} fragment at point and overlay it
over the source code. If there is no fragment at point, process all
fragments in the current entry (between two headlines). When called
with a prefix argument, process the entire subtree. When called with
two prefix arguments, or when the cursor is before the first headline,
process the entire buffer.
@kindex C-c C-c
@item C-c C-c
Remove the overlay preview images.
@end table
During HTML export (@pxref{HTML export}), all La@TeX{} fragments are
converted into images and inlined into the document if the following
setting is active:
@lisp
(setq org-export-with-LaTeX-fragments t)
@end lisp
@node CDLaTeX mode, , Processing LaTeX fragments, Embedded LaTeX
@section Using CDLaTeX to enter math
CDLaTeX-mode is a minor mode that is normally used in combination with a
major LaTeX mode like AUCTeX in order to speed-up insertion of
environments and math templates. Inside Org-mode, you can make use of
some of the features of cdlatex-mode. You need to install
@file{cdlatex.el} and @file{texmathp.el} (the latter comes also with
AUCTeX) from @url{http://www.astro.uva.nl/~dominik/Tools/cdlatex}.
Don't turn cdlatex-mode itself under Org-mode, but use the light
version @code{org-cdlatex-mode} that comes as part of Org-mode. Turn it
on for the current buffer with @code{M-x org-cdlatex-mode}, or for all
Org-mode files with
@lisp
(add-hook 'org-mode-hook 'turn-on-org-cdlatex)
@end lisp
When this mode is enabled, the following features are present (for more
details see the documentation of cdlatex-mode):
@itemize @bullet
@kindex C-c @{
@item
Environment templates can be inserted with @kbd{C-c @{}.
@item
@kindex @key{TAB}
The @key{TAB} key will do template expansion if the cursor is inside a
LaTeX fragment@footnote{Org-mode has a method to test if the cursor is
inside such a fragment, see the documentation of the function
@code{org-inside-LaTeX-fragment-p}.}. For example, @key{TAB} will
expand @code{fr} to @code{\frac@{@}@{@}} and position the cursor
correctly inside the first brace. Another @key{TAB} will get you into
the second brace. Even outside fragments, @key{TAB} will expand
environment abbreviations at the beginning of a line. For example, if
you write @samp{equ} at the beginning of a line and press @key{TAB},
this abbreviation will be expanded to an @code{equation} environment.
To get a list of all abbreviations, type @kbd{M-x cdlatex-command-help}.
@item
@kindex _
@kindex ^
Pressing @kbd{_} and @kbd{^} inside a LaTeX fragment will insert these
characters together with a pair of braces. If you use @key{TAB} to move
out of the braces, and if the braces surround only a single character or
macro, they are removed again (depending on the variable
@code{cdlatex-simplify-sub-super-scripts}).
@item
@kindex `
Pressing the backquote @kbd{`} followed by a character inserts math
macros, also outside LaTeX fragments. If you wait more than 1.5 seconds
after the backquote, a help window will pop up.
@item
@kindex '
Pressing the normal quote @kbd{'} followed by another character modifies
the symbol before point with an accent or a font. If you wait more than
1.5 seconds after the backquote, a help window will pop up. Character
modification will work only inside La@TeX{} fragments, outside the quote
is normal.

Org-mode documents can be exported into a variety of other formats. For
printing and sharing of notes, ASCII export produces a readable and
simple version of an Org-mode file. HTML export allows you to publish a
notes file on the web, while the XOXO format provides a solid base for
exchange with a broad range of other applications. To incorporate

creates only top level headlines and does the rest as items. When
headlines are converted to items, the indentation of the text following
the headline is changed to fit nicely under the item. This is done with
the assumption that the first bodyline indicates the base indentation of
the body text. Any indentation larger than this is adjusted to preserve
the layout relative to the first line. Should there be lines with less
indentation than the first, these are left alone.

Org-mode contains an HTML (XHTML 1.0 strict) exporter with extensive
HTML formatting, in ways similar to John Grubers @emph{markdown}
language, but with additional support for tables.

@cindex active region
@cindex transient-mark-mode

@kindex C-c C-e v h
@kindex C-c C-e v b
@item C-c C-e v h
@item C-c C-e v b
Export only the visible part of the document.
@end table
@cindex headline levels, for exporting
In the exported version, the first 3 outline levels will become
headlines, defining a general document structure. Additional levels
will be exported as itemized lists. If you want that transition to occur
at a different level, specify it with a prefix argument. For example,
@example
@kbd{C-2 C-c C-e b}
@end example
@noindent
creates two levels of headings and does the rest as items.
If you want to include HTML tags which should be interpreted as such,
mark them with @samp{@@} as in @samp{@@<b>bold text@@</b>}.
Plain @samp{<} and @samp{>} are always transformed to @samp{&lt;} and
@samp{&gt;} in HTML export.
@cindex links, in HTML export
@cindex internal links, in HTML export
@cindex external links, in HTML export
Internal links (@pxref{Internal links}) will continue to work in HTML
files only if they match a dedicated @samp{<<target>>}. Automatic links
created by radio targets (@pxref{Radio targets}) will also work in the
HTML file. Links to external files will still work if the HTML file is
in the same directory as the Org-mode file. Links to other @file{.org}
files will be translated into HTML links under the assumption that an
HTML version also exists of the linked file. For information related to
linking files while publishing them to a publishing directory see
@ref{Publishing links}.
You can also give style information for the exported file. The HTML
exporter assigns the following CSS classes to appropriate parts of the
document - your style specifications may change these:
@example
.todo @r{TODO keywords}
.done @r{the DONE keyword}
.timestamp @r{time stamp}
.timestamp-kwd @r{keyword associated with a time stamp, like SCHEDULED}
.tag @r{tag in a headline}
.target @r{target for links}
@end example
The default style specification can be configured through the option
@code{org-export-html-style}. If you want to use a file-local style,
you may use file variables, best wrapped into a COMMENT section at the
end of the outline tree. For example:
@example
* COMMENT HTML style specifications
# Local Variables:
# org-export-html-style: " <style type=\"text/css\">
# p @{font-weight: normal; color: gray; @}
# h1 @{color: black; @}
# </style>"
# End:
@end example
Remember to execute @kbd{M-x normal-mode} after changing this to make
the new style visible to Emacs. This command restarts org-mode for the
current buffer and forces Emacs to re-evaluate the local variables
section in the buffer.

Some people like to use Org-mode for keeping track of projects, but
still prefer a standard calendar application for anniversaries and
appointments. In this case it can be useful to have deadlines and
other time-stamped items in Org-mode files show up in the calendar
application. Org-mode can export calendar information in the standard
iCalendar format.
@table @kbd
@kindex C-c C-e i
@item C-c C-e i
Create iCalendar entries for the current file and store them in the same
directory, using a file extension @file{.ics}.
@kindex C-c C-e I
@item C-c C-e I
Like @kbd{C-c C-e i}, but do this for all files in
@code{org-agenda-files}. For each of these files, a separate iCalendar
file will be written.
@kindex C-c C-e c
@item C-c C-e c
Create a single large iCalendar file from all files in
@code{org-agenda-files} and write it to the file given by
@code{org-combined-agenda-icalendar-file}.
@end table
How this calendar is best read and updated, depends on the application
you are using. For example, when using iCal under Apple MacOS X, you
could create a new calendar @samp{OrgMode} (the default name for the
calendar created by @kbd{C-c C-e c}, see the variables
@code{org-icalendar-combined-name} and
@code{org-combined-agenda-icalendar-file}). Then set Org-mode to
overwrite the corresponding file
@file{~/Library/Calendars/OrgMode.ics}. You may even use AppleScript
to make iCal re-read the calendar files each time a new version of
@file{OrgMode.ics} is produced. Here is the setup needed for this:
@cindex applescript, for calendar update
@lisp
(setq org-combined-agenda-icalendar-file

@subsection The variable @code{org-publish-project-alist}
@cindex org-publish-project-alist
@cindex projects, for publishing
Org-publish is configured almost entirely through setting the value of
one variable, called @code{org-publish-project-alist}.
Each element of the list configures one project, and may be in one of
the two following forms:
@lisp
("project-name" :property value :property value ...)
@r{or}
("project-name" :components ("project-name" "project-name" ...))
@end lisp
In both cases, projects are configured by specifying property values.
A project defines the set of files that will be published, as well as
the publishing configuration to use when publishing those files. When
a project takes the second form listed above, the individual members
of the ``components'' property are taken to be components of the
project, which group together files requiring different publishing
options. When you publish such a ``meta-project'' all the components
will also publish.
@node Sources and destinations, Selecting files, Project alist, Configuration
@subsection Sources and destinations for files

@subsection Publishing Action
@cindex action, for publishing
Publishing means that a file is copied to the destination directory and
possibly transformed in the process. The default transformation is to
export Org-mode files as HTML files, and this is done by the function
@code{org-publish-org-to-html} which calls the HTML exporter
(@pxref{HTML export}). Other files like images only need to be copied
to the publishing destination. For non-Org-mode files, you need to
specify the publishing function.
@multitable @columnfractions 0.3 0.7
@item @code{:publishing-function}
@tab Function executing the publication of a file.
@end multitable
The function must accept two arguments: a property list containing at
least a @code{:publishing-directory} property, and the name of the file
to be published. It should take the specified file, make the necessary
transformation (if any) and place the result into the destination folder.
You can write your own publishing function, but @code{org-publish}

@node Publishing links, Project page index, Publishing options, Configuration
@subsection Links between published files
@cindex links, publishing
To create a link from one Org-mode file to another, you would use
something like @samp{[[file:foo.org][The foo]]} or simply
@samp{file:foo.org.} (@pxref{Hyperlinks}). Upon publishing this link
becomes a link to @file{foo.html}. In this way, you can interlink the
pages of your "org web" project and the links will work as expected when
you publish them to HTML.
You may also link to related files, such as images. Provided you are
careful with relative pathnames, and provided you have also configured
org-publish to upload the related files, these links will work
too. @ref{Complex example} for an example of this usage.
Sometime an Org-mode file to be published may contain links that are
only valid in your production environment, but not in the publishing
location. In this case, use the property
@multitable @columnfractions 0.4 0.6
@item @code{:link-validation-function}
@tab Function to validate links
@end multitable
@noindent
to define a function for checking link validity. This function must
accept two arguments, the file name and a directory relative to which
the file name is interpreted in the production environment. If this
function returns @code{nil}, then the HTML generator will only insert a
description into the HTML file, but no link. One option for this
function is @code{org-publish-validate-link} which checks if the given
file is part of any project in @code{org-publish-project-alist}.
@node Project page index, , Publishing links, Configuration

@subsection Example: complex publishing configuration
This more complicated example publishes an entire website, including
org files converted to HTML, image files, emacs lisp source code, and
stylesheets. The publishing-directory is remote and private files are
excluded.
To ensure that links are preserved, care should be taken to replicate
your directory structure on the web server, and to use relative file
paths. For example, if your org files are kept in @file{~/org} and your
publishable images in @file{~/images}, you'd link to an image with
@c
@example
file:../images/myimage.png
@end example
@c
On the web server, the relative path to the image should be the
same. You can accomplish this by setting up an "images" folder in the
right place on the webserver, and publishing images to it.

@table @kbd
@item #+STARTUP:
This line sets options to be used at startup of org-mode, when an
Org-mode file is being visited. The first set of options deals with the
initial visibility of the outline tree. The corresponding variable for
global default settings is @code{org-startup-folded}, with a default
value @code{t}, which means @code{overview}.

Here are the options for hiding leading stars in outline headings. The
corresponding variables are @code{org-hide-leading-stars} and
@code{org-odd-levels-only}, both with a default setting @code{nil}
(meaning @code{showstars} and @code{oddeven}).
@example
hidestars @r{make all but one of the stars starting a headline invisible.}
showstars @r{show all stars starting a headline}
odd @r{allow only odd outline levels (1,3,...)}
oddeven @r{allow all outline levels}
@end example
@item #+SEQ_TODO: #+TYP_TODO:
These lines set the TODO keywords and their interpretation in the
current file. The corresponding variables are @code{org-todo-keywords}
and @code{org-todo-interpretation}.
@item #+TAGS: TAG1(c1) TAG2(c2)
These lines (several such lines are allowed) specify the legal tags in
this file, and (potentially) the corresponding @emph{fast tag selection}
keys. The corresponding variable is @code{org-tag-alist}.
@item #+CATEGORY:
This line sets the category for the agenda file. The category applies
for all subsequent lines until the next @samp{#+CATEGORY} line, or the
end of the file.
@item #+TBLFM:
This line contains the formulas for the table directly above the line.
@item #+TITLE:, #+AUTHOR:, #+EMAIL:, #+LANGUAGE:, #+TEXT:, #+OPTIONS:
These lines provide settings for exporting files. For more details see

The key @kbd{C-c C-c} has many purposes in org-mode, which are all
mentioned scattered throughout this manual. One specific function of
this key is to add @emph{tags} to a headline (@pxref{Tags}). In many
other circumstances it means something like @emph{Hey Org-mode, look
here and update according to what you see here}. Here is a summary of
what this means in different contexts.
@itemize @minus
@item
If there are highlights in the buffer from the creation of a sparse
tree, or from clock display, remove these highlights.
@item
If the cursor is in one of the special @code{#+KEYWORD} lines, this
triggers scanning the buffer for these lines and updating the
information.
@item
If the cursor is inside a table, realign the table. This command
works even if the automatic table editor has been turned off.
@item
If the cursor is on a @code{#+TBLFM} line, re-apply the formulas to
the entire table.
@item
If the cursor is inside a table created by the @file{table.el} package,
activate that table.
@item
If the current buffer is a remember buffer, close note and file it.
with a prefix argument, file it without further interaction to the default
location.
@item
If the cursor is on a @code{<<<target>>>}, update radio targets and
corresponding links in this buffer.

If the cursor is in a plain list item with a checkbox, toggle the status
of the checkbox.
@item
If the cursor is on a numbered item in a plain list, renumber the

@section A cleaner outline view
@cindex hiding leading stars
@cindex clean outline view
Some people find it noisy and distracting that the Org-mode headlines
are starting with a potentially large number of stars. For example
the tree from @ref{Headlines}:
@example
* Top level headline
** Second level
*** 3rd level
some text
*** 3rd level
more text
* Another top level headline
@end example
@noindent
Unfortunately this is deeply ingrained into the code of Org-mode and
cannot be easily changed. You can, however, modify the display in such
a way that all leading stars become invisible and the outline more easy
to read. To do this, customize the variable
@code{org-hide-leading-stars} like this:
@lisp
(setq org-hide-leading-stars t)
@end lisp
@noindent
or change this on a per-file basis with one of the lines (anywhere in
the buffer)
@example
#+STARTUP: showstars
#+STARTUP: hidestars
@end example
@noindent
Press @kbd{C-c C-c} with the cursor in a @samp{STARTUP} line to activate
the modifications.
With stars hidden, the tree becomes:
@example
* Top level headline
* Second level
* 3rd level
some text
* 3rd level
more text
* Another top level headline
@end example
@noindent
Note that the leading stars are not truly replaced by whitespace, they
are only fontified with the face @code{org-hide} that uses the
background color as font color. If are are not using either white or
black background, you may have to customize this face to get the wanted
effect. Another possibility is to set this font such that the extra
stars are @i{almost} invisible, for example using the color
@code{grey90} on a white background.
Things become cleaner still if you skip all the even levels and use only
odd levels 1, 3, 5..., effectively adding two stars to go from one
outline level to the next:
@example
* Top level headline
* Second level
* 3rd level
some text
* 3rd level
more text
* Another top level headline
@end example
@noindent
In order to make the structure editing and export commands handle this
convention correctly, use
@lisp
(setq org-odd-levels-only t)
@end lisp
@noindent
or set this on a per-file basis with one of the following lines (don't
forget to press @kbd{C-c C-c} with the cursor in the startup line to
activate changes immediately).
@example
#+STARTUP: odd
#+STARTUP: oddeven
@end example
You can convert an Org-mode file from single-star-per-level to the
double-star-per-level convention with @kbd{M-x org-convert-to-odd-levels
RET} in that file. The reverse operation is @kbd{M-x
org-convert-to-oddeven-levels}.

@section Using org-mode on a tty
@cindex tty keybindings
Org-mode uses a number of keys that are not accessible on a tty. This
applies to most special keys like cursor keys, @key{TAB} and
@key{RET}, when these are combined with modifier keys like @key{Meta}
and/or @key{Shift}. Org-mode uses these bindings because it needs to
provide keys for a large number of commands, and because these keys
appeared particularly easy to remember. In order to still be able to
access the core functionality of Org-mode on a tty, alternative
bindings are provided. Here is a complete list of these bindings,
which are obviously more cumbersome to use. Note that sometimes a
work-around can be better. For example changing a time stamp is
really only fun with @kbd{S-@key{cursor}} keys. On a tty you would
rather use @kbd{C-c .} to re-insert the timestamp.

@cindex @file{calc.el}
@item @file{calc.el} by Dave Gillespie
Org-mode uses the calc package for implementing spreadsheet
functionality in its tables (@pxref{Table calculations}). Org-modes
checks for the availability of calc by looking for the function
@code{calc-eval} which should be autoloaded in your setup if calc has
been installed properly. As of Emacs 22, calc is part of the Emacs
distribution. Another possibility for interaction between the two
packages is using calc for embedded calculations. @xref{Embedded Mode,
, Embedded Mode, calc, GNU Emacs Calc Manual}.
@cindex @file{constants.el}
@item @file{constants.el} by Carsten Dominik
In a table formula (@pxref{Table calculations}), it is possible to use
names for natural constants or units. Instead of defining your own
constants in the variable @code{org-table-formula-constants}, install
the @file{constants} package which defines a large number of constants
and units, and lets you use unit prefixes like @samp{M} for
@samp{Mega} etc. You will need version 2.0 of this package, available
at @url{http://www.astro.uva.nl/~dominik/Tools}. Org-mode checks for
the function @code{constants-get}, which has to be autoloaded in your
setup. See the installation instructions in the file
@file{constants.el}.

Startup of Org-mode may fail with the error message
@code{(wrong-type-argument keymapp nil)} when there is an outdated
version @file{allout.el} on the load path, for example the version
distributed with Emacs 21.x. Upgrade to Emacs 22 and this problem will
disappear. If for some reason you cannot do this, make sure that org.el
is loaded @emph{before} @file{allout.el}, for example by putting
@code{(require 'org)} early enough into your @file{.emacs} file.
@cindex @file{CUA.el}
@item @file{CUA.el} by Kim. F. Storm
Keybindings in Org-mode conflict with the @kbd{S-<cursor>} keys
used by CUA-mode (as well as pc-select-mode and s-region-mode) to
select and extend the region. If you want to use one of these
packages along with Org-mode, configure the variable
@code{org-CUA-compatible}. When set, Org-mode will move the following
keybindings in org-mode files, and in the agenda buffer (but not
during date selection).
@example
S-UP -> M-p S-DOWN -> M-n
S-LEFT -> M-- S-RIGHT -> M-+
S-RET -> C-S-RET

Yes, these are unfortunately more difficult to remember. If you want

Here is a list of things that should work differently, but which I
have found too hard to fix.
@itemize @bullet
@item
If a table field starts with a link, and if the corresponding table
column is narrowed (@pxref{Narrow columns}) to a width too small to
display the link, the field would look entirely empty even though it is
not. To prevent this, Org-mode throws an error. The work-around is to
make the column wide enough to fit the link, or to add some text (at
least 2 characters) before the link in the same field.
@item
Narrowing table columns does not work on XEmacs, because the
@code{format} function does not transport text properties.
@item
Text in an entry protected with the @samp{QUOTE} keyword should not
autowrap.
@item
When the application called by @kbd{C-c C-o} to open a file link fails
(for example because the application does not exist or refuses to open
the file), it does so silently. No error message is displayed.
@item
The remote-editing commands in the agenda buffer cannot be undone with
@code{undo} called from within the agenda buffer. But you can go to
the corresponding buffer (using @key{TAB} or @key{RET} and execute
@code{undo} there.
@item
Recalculating a table line applies the formulas from left to right.
If a formula uses @emph{calculated} fields further down the row,
multiple recalculation may be needed to get all fields consistent.
@item
A single letter cannot be made bold, for example @samp{*a*}.

The exporters work well, but could be made more efficient.

This package implements extended mouse functionality for Org-mode. It
allows you to cycle visibility and to edit the document structure with
the mouse. Best of all, it provides a context-sensitive menu on
@key{mouse-3} that changes depending on the context of a mouse-click.

@node Dynamic blocks, , Extensions, Extensions and Hacking
@section Dynamic blocks
Org-mode documents can contain @emph{dynamic blocks}. These are
specially marked regions that are updated by some user-written
function. A good example for such a block is the clock table inserted
by the command @kbd{C-c C-x C-r} (@pxref{Clocking work time}).
Dynamic block are enclosed by a BEGIN-END structure that assigns a name
to the block and can also specify parameters for the function producing
the content of the block.
@example
#+BEGIN: myblock :parameter1 value1 :parameter2 value2 ...
#+END:
@end example
Dynamic blocks are updated with the following commands
@table @kbd
@kindex C-c C-x C-u
@item C-c C-x C-u
Update dynamic block at point.
@kindex C-u C-c C-x C-u
@item C-u C-c C-x C-u
Update all dynamic blocks in the current file.
@end table
Updating a dynamic block means to remove all the text between BEGIN and
END, parse the BEGIN line for parameters and then call the specific
writer function for this block to insert the new content. For a block
with name @code{myblock}, the writer function is
@code{org-dblock-write:myblock} with as only parameter a property list
with the parameters given in the begin line. Here is a trivial example
of a block that keeps track of when the block update function was last
run:
@example
#+BEGIN: block-update-time :format "on %m/%d/%Y at %H:%M"
#+END:
@end example
@noindent
The corresponding block writer function could look like this:
@lisp
(defun org-dblock-write:block-update-time (params)
(let ((fmt (or (plist-get params :format) "%d. %m. %Y")))
(insert "Last block update at: "
(format-time-string fmt (current-time)))))
@end lisp
If you want to make sure that all dynamic blocks are always up-to-date,
you could add the function @code{org-update-all-dblocks} to a hook, for
example @code{before-save-hook}. @code{org-update-all-dblocks} is
written in a way that is does nothing in buffers that are not in Org-mode.

@cindex acknowledgments
@cindex history
@cindex thanks
The beginnings of Org-mode go back to 2003. It was borne out of
frustration over the user interface of the emacs outline-mode. All I
wanted was to make working with an outline tree possible without having
to remember more than 10 commands just for hiding and unhiding parts of
the outline tree, and to allow to restructure a tree easily. Visibility
cycling and structure editing were originally implemented in the package
@file{outline-magic.el}, but quickly moved to the more general
@file{org.el}. TODO entries, basic time stamps, and table support were
added next, and highlight the two main goals that Org-mode still has
today: To create a new, outline-based, plain text mode with innovative
and intuitive editing features, and to incorporate project planning
functionality directly into a notes file.
Since the first release, hundreds of emails to me or on
@code{emacs-orgmode@@gnu.org} have provided a constant stream of bug
reports, feedback, new ideas, and sometimes even patches and add-on
code. Many thanks to everyone who has helped to improve this package.
I am trying to keep here a list of the people who had significant
influence in shaping one or more aspects of Org-mode. The list may not
be complete, if I have forgotten someone, please accept my apologies and
let me know.
