See Emacs Lisp manual where it speaks about macros. You would do: F3 to start recording macro, then you do necessary actions like commenting the page. Press F4 to save macro. Apply F4 in any buffer you wish. Use `C-x C-k n' to name the last recorded macro. Then you can save the macro into buffer and then into file: (fset 'comment (kmacro-lambda-form [?\M-< ?\M-x ?r ?e ?p ?l ?a ?c tab ?r ?e ?g ?e tab return ?^ return ?\; ?\; ? return] 0 "%d")) That is what I did above for commenting first lines with ;; and named the macro comment. If you evaluate the above or load it from init.el or other file, you can then invoke macro with: M-x comment RET and it will do what you wanted. Jean
