If cmd1 changes it, anything can happen. e.g. (global-set-key (kbd "") (lambda () (interactive) (yffoo))) (defun yffoo () (setq current-prefix-arg '(5)) (call-interactively 'yfbar)) (defun yfbar (&optional arg) (interactive "P") (message "arg is %S" arg)) hitting f6 will show that arg is (5) (which doesn't make sense in an true interactive call) -- Nico.
