`M-x set-variable' is limited to user option variables, but you can set any variable with a Lisp expression, using the function `setq'.

 Examining and Setting Variables
---------------------------------
`C-h v VAR <RET>'
     Display the value and documentation of variable VAR
     (`describe-variable').

`M-x set-variable <RET> VAR <RET> VALUE <RET>'
     Change the value of variable VAR to VALUE.

   `M-x set-variable' is limited to user option variables, but you can
set any variable with a Lisp expression, using the function `setq'.
Here is a `setq' expression to set `fill-column':

     (setq fill-column 75)

(setq message-log-max 2000)

message-log-max specifies how many lines Messages can contain

To record keystrokes, type “Ctrl+x (” then start typing your keystrokes. When done, type “Ctrl+x )”. This records your keystrokes. To run the keystrokes you've recorded, type “Ctrl+x e”.

Here are the command names and their shortcuts:

start-kbd-macro            Ctrl+x (
end-kbd-macro              Ctrl+x )
call-last-kbd-macro        Ctrl+x e

If you want to use your keyboard macro for future use, you can save it. To save the macro, first type “Alt+x name-last-kbd-macro”, then type “Alt+x insert-kbd-macro”, which will insert the lisp code for the keyboard macro at the cursor point. Put the code in your emacs init file (usually at “~/.emacs”). Then, you can execute your keyboard macro like this: “Alt+x yourMacroName” the next time you start emacs.

To find the key code for a particular key, You can use

then look at the next examples on how to use the function global-set-key

 Indent all the files in a project using emacs

Use find's exec and reduce the need for multiple evals with a progn wrapper.

lst=`find . -iname \*.c -or -iname \*.h`; for i in $lst; do emacs -nw -q $i --eval "(mark-whole-buffer)" --eval "(indent-region (point-min) (point-max) nil)" --eval "(save-buffer)" --kill; done

find . -iname \*.c -or -iname \*.h -exec emacs -nw -q {} --eval "(progn (mark-whole-buffer) (indent-region (point-min) (point-max) nil) (save-buffer))" --kill \;
