\title{GNU\ \ Emacs\ \ Survival\ \ Card}{for version 21}

In the following, \kbd{C-z} means hit the `\kbd{z}' key while
holding down the {\it Ctrl}\ \ key. \kbd{M-z} means hit the
`\kbd{z}' key while hitting the {\it Meta\/} (labeled {\it Alt\/}
on some keyboards) or after hitting {\it Esc\/} key.

\section{Running Emacs}

To enter GNU Emacs, just type its name: \kbd{emacs}.
Emacs divides the frame into several areas:
  menu line,
  buffer area with the edited text,
  mode line describing the buffer in the window above it,
  and a minibuffer/echo area in the last line.
\askip
\key{C-x C-c} quit Emacs
\key{C-x C-f} edit file; this command uses the minibuffer to read
  the file name; use this to create new files by entering the name
  of the new file
\key{C-x C-s} save the file
\key{C-x k} kill a buffer
\key{C-g} in most context: cancel, stop, abort partially typed or
  executing command
\key{C-x u} undo

\section{Moving About}

\key{C-l} scroll current line to center of window
\key{C-x b} switch to another buffer
\key{M-<} move to beginning of buffer
\key{M->} move to end of buffer
\key{M-x goto-line} go to a given line number

\section{Multiple Windows}

\key{C-x 0} remove the current window from the display
\key{C-x 1} make active window the only window
\key{C-x 2} split window horizontally
\key{C-x 3} split window vertically
\key{C-x o} move to other window

\section{Regions}

Emacs defines a `region' as the space between the {\it mark\/} and
the {\it point}. A mark is set with \kbd{C-{\it space}}.
The point is at the cursor position.
\askip
\key{M-h} mark entire paragraph
\key{C-x h} mark entire buffer

\section{Killing and Copying}

\key{C-w} kill region
\key{M-w} copy region to kill-ring
\key{C-k} kill from the cursor all the way to the end of the line
\key{M-DEL} kill word
\key{C-y} yank back the last kill (\kbd{C-w C-y} combination could be
  used to move text around)
\key{M-y} replace last yank with previous kill

\section{Searching}

\key{C-s} search for a string
\key{C-r} search for a string backwards
\key{RET} quit searching
\key{M-C-s} regular expression search
\key{M-C-r} reverse regular expression search
\askip
Use \kbd{C-s} or \kbd{C-r} again to repeat the search in either direction.

\section{Tags}

Tags tables files record locations of function and
procedure definitions, global variables, data types and anything
else convenient. To create a tags table file, type
`{\tt etags} {\it input\_files}' as a shell command.
\askip
\key{M-.} find a definition
\key{C-u M-.} find next occurrence of definition
\key{M-*} pop back to where \kbd{M-.} was last invoked
\mkey{M-x tags-query-replace} run query-replace on all files
  recorded in tags table
\key{M-,} continue last tags search or query-replace

\section{Compiling}

\key{C-c C-c} go to the next compiler error, when in
  the compile window or
\key{C-x `} when in the window with source code

\key{C-x d} invoke Dired
\key{d} flag this file for deletion
\key{\~{}} flag all backup files for deletion

\key{g} update the Dired buffer
\key{f} visit the file described on the current line
\key{s} switch between alphabetical date/time order

\section{Reading and Sending Mail}

\key{DEL} skip to next without replacing
\key{!} replace all remaining matches
