General
Use features in other modes
I would like to use editing features of org-mode in other modes, is this possible?
Not really. For tables there is orgtbl-mode which implements the
table editor as a minor mode. For other features you need to switch to
Org-mode temporarily, or prepare text in a different buffer.
Visibility cycling in Outline-mode and Outline-minor-mode
Can I get the visibility-cycling features in outline-mode and outline-minor-mode?
Yes, these functions are written in a way that they are independent of
the outline setup. The following setup provides standard Org-mode
functionality in outline-mode on TAB and S-TAB. For
outline-minor-mode, we use C-TAB instead of TAB,
because TAB usually has mode-specific tasks.
:(add-hook 'outline-minor-mode-hook
(lambda () (define-key outline-minor-mode-map [(control tab)] 'org-cycle) (define-key outline-minor-mode-map [(shift tab)] 'org-global-cycle)))
:(add-hook 'outline-mode-hook
(lambda () (define-key outline-mode-map [(tab)] 'org-cycle) (define-key outline-mode-map [(shift tab)] 'org-global-cycle)))
Or check out outline-magic.el, which does this and also provides promotion and demotion functionality. outline-magic.el is available at Outline Magic.
Errors
(wrong-type-argument keymapp nil)
When I try to use Org-mode, I always get the error message @code{(wrong-type-argument keymapp nil)}
This is a conflict with an outdated version of the allout.el, see the Conflicts section in the manual
CUA mode does not work with Org-mode
Org-mode takes over the S-cursor keys. I also want to use CUA-mode, is there a way to fix this conflict?
Yes, see the Conflicts section of the manual.
winddmove.el does not work with Org-mode.
Org-mode takes over the S-cursor keys. I also want to use windmove.el, is there a way to fix this conflict?
Yes, see the Conflicts section of the manual.
Setup and Structure
Org-mode as default mode
Org-mode seems to be a useful default mode for the various README files I have scattered through my directories. How do I turn it on for all README files?
Add the following to your .emacs file:
(add-to-list 'auto-mode-alist '("README$" . org-mode))
You can even make it the default mode for any files with unspecified mode using
(setq default-major-mode 'org-mode)
Get rid of extra stars in outline
*All these stars are driving me mad, I just find the Emacs outlines unreadable. Can't you just put white space and a single star as a starter for headlines?*
See the section Clean outline view in the manual.
Two windows on same Org-mode file
I would like to have two windows on the same Org-mode file, but with different outline visibility. Is that possible?
You may use indirect buffers which do exactly this. See the
documentation on the command make-indirect-buffer.
Insert empty lines before new headings and plain list items
I would like to have an empty line before each newly inserted headline, but not before each newly inserted plain-list item.
(setq org-blank-before-new-entry
'((heading . t) (plain-list-item . nil))
Amount of context in sparse trees
*Sparse tree show the headline hierarchy above each match, and also the headline following a match. I'd like to construct more compact trees, with less context.*
Take a look at the variables org-show-hierarchy-above and
org-show-following-headline.
Stacking calls to org-occur
*Each call to org-occur starts again from OVERVIEW and exposes only the matches of the current call. I'd like to combine the effect of several calls*.
You can construct a regular expression that matches all targets you
want. Alternatively, use a C-u prefix with the second and any
further calls to org-occur to keep the current visibility and
highlighting in addition to the new ones.
Hyperlinks
Confirmation for shell and elisp links
*When I am executing shell/elisp links I always get a confirmation prompt and need to type "yes RET", that's 4 key presses! Can I get rid of this?*
The confirmation is there to protect you from unwantingly execute potentially dangerous commands. For example, imagine a link : Google Search
In an Org-mode buffer, this command would look like Google Search, but really it would remove your home directory. If you wish, you can make it easier to respond to the query by setting
(setq org-confirm-shell-link-function 'y-or-n-p
org-confirm-elisp-link-function 'y-or-n-p).
Then a single keypress will be enough to confirm those links. It is also possible to turn off this check entirely, but I strongly recommend against this. Be warned.
Use RET or TAB to follow a link
From other packages like Emacs-wiki, I am used to follow links with
RET when the cursor is on the link. Is this also possible in org-mode?
Yes, and you may also use TAB.
(setq org-return-follows-link t) (setq org-tab-follows-link t)
Clicking on a link without activating it
Each time I click inside a link in order to set point to this location, Org-mode actually follows the link
Activating links with mouse-1 is a new feature in Emacs 22, to make
link behavior similar to other applications like web browsers. If you
hold the mouse button down a bit longer, the cursor will be set
without following the link. If you cannot get used to this behavior,
you can (as in Emacs 21) use mouse-2 to follow links and turn off
link activation for mouse-1 with
(setq org-mouse-1-follows-link nil)
Remember
Can I automatically start the clock when opening a remember template?
Yes, this is possible. Use the following code and make sure that after executing it, `my-start-clock-if-needed' is in `remember-mode-hook' after `org-remember-apply-template'.
(add-hook 'remember-mode-hook 'my-start-clock-if-needed 'append)
(defun my-start-clock-if-needed ()
(save-excursion
(goto-char (point-min))
(when (re-search-forward " *CLOCK-IN *" nil t)
(replace-match "")
(org-clock-in))))
Then, when a template contains the key string CLOCK-IN, the clock will be started. Starting with Org-mode version 5.20, the clock will automatically be stopped when storing the remember buffer.
Export
Make TODO entries items, not headlines in HTML export
*When I export my TODO list, every TODO item becomes a separate section. How do I enforce these items to be exported as an itemized list?*
If you plan to use ASCII or HTML export, make sure things you want to be exported as item lists are level 4 at least, even if that does mean there is a level jump. For example:
* Todays top priorities **** TODO write a letter to xyz **** TODO Finish the paper **** Pick up kids at the school
Alternatively, if you need a specific value for the heading/item
transition in a particular file, use the #+OPTIONS line to
configure the H switch.
#+OPTIONS: H:2; ...
Export only a subtree
I would like to export only a subtree of my file to HTML. How?
If you want to export a subtree, mark the subtree as region and then
export. Marking can be done with C-c @ C-x C-x, for example.
How to import org-mode calendar data into Mac OSX ical
I would like my iCal program on Mac OSX to import the iCalendar file produced by Org-mode. How?
This is for OSX 10.3, see below for 10.4: When using iCal under
Apple MacOS X, you can create a new calendar OrgMode (the default
name for the calendar created by C-c C-e c, see the variables
org-icalendar-combined-name and
org-combined-agenda-icalendar-file). Then set Org-mode to overwrite
the corresponding file ~/Library/Calendars/OrgMode.ics. You may
even use AppleScript to make iCal re-read the calendar files each time
a new version of OrgMode.ics is produced. Here is the setup needed
for this:
(setq org-combined-agenda-icalendar-file
"~/Library/Calendars/OrgMode.ics")
(add-hook 'org-after-save-iCalendar-file-hook
(lambda ()
(shell-command
"osascript -e 'tell application \"iCal\" to reload calendars'")))
For Mac OS X 10.4, you need to write the ics file to
/Library/WebServer/Documents/ and then subscribe iCalendar to
http: //localhost/orgmode.ics
Tables
#ERROR fields in tables
One of my table columns has started to fill up with #ERROR. What
is going on?
Org-mode tried to compute the column from other fields using a
formula stored in the #+TBLFM: line just below the table, and
the evaluation of the formula fails. Fix the fields used in the
formula, or fix the formula, or remove it!
Unwanted new lines in table
*When I am in the last column of a table and just above a horizontal line in the table, pressing TAB creates a new table line before the horizontal line*. How can I quickly move to the line below the horizontal line instead?
Press down (to get on the separator line) and then TAB.
Or configure the variable
(setq org-table-tab-jumps-over-hlines t)
Automatic detection of formulas
I need to use fields in my table that start with "=", and each time I enter such a field, Org-mode thinks this is a formula.
With the setting
(setq org-table-formula-evaluate-inline nil)
this will no longer happen. You can still use formulas using the commands @<tt>C-c =@</tt> and @<tt>C-u C-c =@</tt>
Change indentation of a table
How can I change the indentation of an entire table without fixing every line by hand?
The indentation of a table is set by the first line. So just fix the
indentation of the first line and realign with TAB.
Performance issues with table alignment
I have a huge table in a file, and the automatic realign of tables is just taking too long. What can I do?
Either split the table into several by inserting an empty line every 100 lines or so. Or turn off the automatic re-align with
(setq org-table-automatic-realign nil)
After this the only way to realign a table is to press C-c C-c. It
will no longer happen automatically, removing the corresponding delays
during editing.
Performance issues with table calculation
I have a complex table with lots of formulas, and recomputing the table takes rather long. What can I do?
Nothing, really. The spreadsheet in org is mostly done to make calculations possible, not so much to make them fast. Since Org-mode is firmly committed to the ASCII format, nothing is stopping you from editing the table by hand. Therefore, there is no internal representation of the data. Each time Org-mode starts a computation, it must scan the table for special lines, find the fields etc. This is slow. Furthermore, Calc is slow compared to hardware computations. To make this work with normal editing, recalculation is not happening automatically, or only for the current line, so that the long wait for a full table iteration only happens when you ask for it.
So for really complex tables, moving to a "real" spreadsheet may still be the best option.
That said, there are some ways to optimize things in Org-mode, and I have been thinking about moving a bit further down this line. However, for my applications this has so far not been an issue at all. If you have a good case,you could try to convince me.
Incrementing numbers
*When I press S-RET in a table field to copy its value down, the
content is not copied as is, but it is increased by one.
Is that a bug or a feature*
Well, it is supposed to be a feature, to make it easy to create a column with increasing numbers. If this gets into your way, turn it off with
(setq org-org-table-copy-increment nil)
Agenda
Include Org-mode agenda into Emacs diary
Is it possible to include entries from org-mode files into my emacs diary?
Since the org-mode agenda is much more powerful and can contain the diary, you should think twice before deciding to do this. If you insist, however, integrating Org-mode information into the diary is possible. You need to turn on fancy diary display by setting in .emacs:
(add-hook 'diary-display-hook 'fancy-diary-display)
Then include the following line into your ~/diary file, in
order to get the entries from all files listed in the variable
org-agenda-files
&%%(org-diary)
You may also select specific files with
&%%(org-diary) ~/path/to/some/org-file.org &%%(org-diary) ~/path/to/another/org-file.org
If you now launch the calendar and press @<tt>d@</tt> to display a diary, the
headlines of entries containing a timestamp, date range, schedule, or
deadline referring to the selected date will be listed. Just like
Org-mode's agenda view, the diary for today contains additional
entries for overdue deadlines and scheduled items. See also the
documentation of the org-diary function. Under XEmacs, it is
not possible to jump back from the diary to the org, this works only in
the agenda buffer.
