Yeah, I think the easiest path is to tell the user "don't touch anything". One trick that you could try is to use `special-event-map`. AFAICT from reading the code of `read_char`, this map is consulted for "real" events but not for events coming from `unread-command-events`, so maybe something like: (define-key special-event-map [t] #'my-consume-real-input) (defvar my-stashed-real-input nil) (defun my-consume-real-input () (interactive) (push last-input-event my-stashed-real-input)) Hmm... it looks like the "default binding" feature (i.e. the [t] above) is not used when consulting that `special-event-map`, so that won't work (you'd need a "magic" keymap which has a binding for all possible events). Maybe you should log a feature request with `M-x report-emacs-bug`. Stefan
