The intended audience here is the person who wants to make simple customizations and knows Lisp syntax.
Here are some examples of binding global keys in Emacs Lisp. Note that you cannot say
"\M-\#";
You must say
"\e\#".
(global-set-key "\C-cg" 'goto-line)
(global-set-key "\C-x\C-k" 'kill-region)
(global-set-key "\e\#" 'query-replace-regexp)
An example of setting a variable in Emacs Lisp:
(setq backup-by-copying-when-linked t)
(defun command-name (args)
"documentation"
(interactive "template")
body)
An example:
(defun this-line-to-top-of-window (line)
"Reposition line point is on to top of window. With ARG, put point on line ARG.
Negative counts from bottom."
(interactive "P")
(recenter (if (null line)
0
(prefix-numeric-value line))))
The argument to interactive is a string specifying how to get the arguments when the function is called interactively. Type C-h f interactive for more information.
