Ah, I understand what you mean now -- you want a key that's normally
bound to a different command, but if it's after an abbreviation, it
should expand the abbreviation instead.
Yes, that menu trick does work for that use case, but you could also use
a command like:
(defun my-expand ()
(interactive)
(if (abbrev--before-point)
(expand-abbrev)
(call-interactively
(lookup-key (delq my-override-map (current-active-maps))
(this-command-keys)))))
In any case, I don't think these sort of "chained" keystrokes are very
common -- I think most users would find them somewhat confusing, so I
don't think adding something like this to Emacs would be appropriate.
So I'm closing this bug report.
