Feature Request == Impl Howto question

Feature Request == Impl Howto question

[T.V Raman]

In recent versions of Emacs, if you press a prefix key and wait,
there is a message in the echo area that shows the prefix key that was
pressed.

Feature request: would it be possible to define an event handler from
elisp for this; if so I could use it to play a short sound -- and
preferably with a configurable timeout before that  elisp-handler is
invoked. Is this possible?

Actually, this feature is very old, probably as old as Emacs itself.

You mean, to call a hook when we display that?  Should be easy, I
think; patches welcome.

The timeout is already configurable, see the variable echo-keystrokes.

Thanks for the echo-keystrokes pointer, was exactly (and all) that I
needed.

I think I added this feature to the original Emacs in 1976-77.

thanks for that:-)

It had entirely slipped me by for 30+ years because I only recently
speech-enabled set-minibuffer-message
which meant I finally heard it. Moreover that message by default
triggers based on the setting of echo-keystrokes (default is 2) and it
turns out I never waited that long. So now I have echo-keystrokes 0.01
and am happy!
