Hi I'd like to detect whether prefix arguments of a command are supplied by C-u or otherwise. My idea is to use this-command-keys and compare it to some string, like the following pseudo code: (defun bla (arg) (interactive "p") (when (string= "C-u" (substring (this-command-keys) 0 2)) (message "hurray"))) I just don't understand how to compare key sequences. Or maybe there's better way of doing it? -- Best wishes H. Dieter Wilhelm Darmstadt, Germany
