It is one more case where I think emacs should provide a binding of
the form C-x C-+ + + + + ...
'+' would mean "repeat last command" as long as no other key is hit.
Additionnaly, we could declare "-" as a valid candidate.
Why not :
(global-set-key-autorepeat '("\C-x\C-" . ("+" . zoom-in)
("-" . zoom-out)))
to allow auto-repeat on + and - after either C-x C-- or C-x C-+.
I'd be happy if emacs could provide a primitive for this. It could
display a transient helper in the echo area to remind what keys are
temporary bound to special functions.
Currently, I use the following code :
;;;; Auto-repeat any command by pressing last shortcut key
(defun auto-repeat-command (command)
(let ((repeat-repeat-char
(when (eq last-command-char
last-command-event)
last-command-char)))
(call-interactively command)
(while (eq (read-event) repeat-repeat-char)
;; Make each repetition undo separately.
(auto-repeat-command command)
(setq unread-command-events (list last-input-event)))))
then, for example :
(global-set-key "\C-xmn" (lambda () (interactive) (auto-repeat-command
'marker-visit-next)))
This is clearly not optimal, but it works and I have not looked for a
cleaner implementation, yet.
This type of binding is ideal for any command that :
- is not very often called
- when called, will probably be called several time in a row
They are a lot of places where such default behaviour would provide
intuitive and non-intrusive bindings.
What do you think ?
