Pressing C-h in the middle of a key sequence shows what's possible
next. Is there a standard framework, for doing some thing similar,
without invoking C-h? That is -- always provide the user with
feedback as to what key chord is possible next. The help window
should disappear once input is complete successfully or aborted.
(defvar my-map (make-sparse-keymap))
(define-key my-map [(control c) (a)] 'a-func)
(define-key my-map [(control c) (b)] 'b-func)
(defun cool-fun (func)
""
(interactive (magic-input-helper my-map))
The magic-input-helper is what I'm after here. It seems this should
be a generally helpful function.

In the middle of any key sequence, or even before hitting any prefix key.
Help on all/any of the keys that can be used in the current context.
Get a list of all possible completions for a key. Get full help on any of them
(command description, in *Help*). End by completing a key if you want to use
it, or `C-g' if you were just after the info.

I don't believe there's a standard framework, but for example org-mode
uses "dispatchers" for org-agenda, org-capture and org-export, where you
hit a key and are presented with a menu of options, you could take a
look at how that's done. It won't be so simple as `magic-input-helper',
unfortunately.

I have been using one-key.el library for 2 years now and I'm very happy with
it. It is all explained on Emacs Wiki

Very cool. This looks almost exactly like what I wanted. Thank you.
