% This file is intended to be processed by plain TeX (TeX82).

|

% The final reference card has six columns, three on each side.
|
||
% This file can be used to produce it in any of three ways:
|
||
% 1 column per page
|
||
% produces six separate pages, each of which needs to be reduced to 80%.
|
||
% This gives the best resolution.
|
||
% 2 columns per page
|
||
% produces three already-reduced pages.
|
||
% You will still need to cut and paste.
|
||
% 3 columns per page
|
||
% produces two pages which must be printed sideways to make a
|
||
% ready-to-use 8.5 x 11 inch reference card.
|
||
% For this you need a dvi device driver that can print sideways.
|
||
% Which mode to use is controlled by setting \columnsperpage.
|
||
%
|
||
% To compile and print this document:
|
||
% tex refcard.tex
|

% dvips -t landscape refcard.dvi

|

|
||
\section{Key Binding Notation}
|
||
|
||
In the Emacs key binding notation, \kbd{C-x}
|
||
is \kbd{Ctrl+X}; \kbd{M-x} is usually \kbd{Alt+X}; \kbd{S-x} is
|
||
\kbd{Shift+X}; and \kbd{C-M-x} is \kbd{Ctrl+Alt+X}, etc.
|
||
|
||
\section{Leaving Emacs}
|
||
|
||
\key{iconify Emacs (or suspend it in terminal)}{C-z}
|
||
\key{exit Emacs permanently}{C-x C-c}
|

\section{Files}
|
||
|

\key{{\bf read} a file into Emacs}{C-x C-f}

\key{write buffer to a specified file}{C-x C-w}
|
||
\key{toggle read-only status of buffer}{C-x C-q}
|
||
|
||
\section{Getting Help}
|
||
|
||
The help system is simple. Type \kbd{C-h} (or \kbd{F1}) and follow
|
||
the directions. If you are a first-time user, type \kbd{C-h t} for a
|
||
{\bf tutorial}.

||
\key{exit incremental search}{RET}
|
||
\key{undo effect of last character}{DEL}
|
||
\key{abort current search}{C-g}
|
||
|
||
Use \kbd{C-s} or \kbd{C-r} again to repeat the search in either direction.
|
||
If Emacs is still searching, \kbd{C-g} cancels only the part not matched.

Making global key bindings in Emacs Lisp (example):
|
||
|
||
\beginexample%
|
||
(global-set-key (kbd "C-c g") 'search-forward)
|
||
(global-set-key (kbd "M-\#") 'query-replace-regexp)

\section{Writing Commands}

(defun \<command-name> (\<args>)
|
||
"\<documentation>" (interactive "\<template>")
|
||
\<body>)
|
||
\endexample
|
||
|
||
An example:
|
||
|
||
\beginexample%
|
||
(defun this-line-to-top-of-window (line)
|
||
"Reposition current line to top of window.
|
||
With prefix argument LINE, put point on LINE."
|
||
(interactive "P")
|
||
(recenter (if (null line)
|
||
0
|
||
(prefix-numeric-value line))))
|
||
\endexample
|
||
|
||
The \kbd{interactive} spec says how to read arguments interactively.
|
