+ \title{GNU\ \ Emacs\ \ Survival\ \ Card}{for version \versionemacs}
+
+ 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

+
+ \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.

+ \key{M-h} mark entire paragraph
+ \key{C-x h} mark entire buffer
+
+ \section{Killing and Copying}

+ 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.

+ \key{M-.} find a definition
