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
