That's really nice thanks, I've added it to my configuration, with also
two functions to enable/disable it.
I have to use setq-default to disable it by the way, is that correct?
--8<---------------cut here---------------start------------->8---
(defun growl-mode-off ()
(interactive)
(setq-default pre-command-hook (remq 'popup-last pre-command-hook)))
--8<---------------cut here---------------end--------------->8---
Only one more problem, here I display all the keys, but I don't really
care about stuff like
"C-n", "C-p", "m" (all the keys are inserted).
Is there any kind of distinction between simple and more complex
combinations?
