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?
