To carry out commands using the keyboard instead of the pull-down
menus, you can bind commands to certain key sequences. This is done
by specifying the key sequence and command in your .emacs file. For
example:
(global-set-key \C-l
'goto-line) ;; enables you to go to a certain line by typing ctrl-l
and then the line number
(global-set-key \C-p
'query-replace);; maps query-replace to control-p
