% 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 above.

To enter GNU Emacs \versionemacs, just type its name: \kbd{emacs}

\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{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 (examples):
|
||
|
||
\beginexample%
|
||
(global-set-key "\\C-cg" 'goto-line)
|
||
(global-set-key "\\M-\#" 'query-replace-regexp)

An example:
|

(defun this-line-to-top-of-window (line)
|

(interactive "P")
|

(recenter (if (null line)
|

(prefix-numeric-value line))))
