FWIW - `M-?' is what Icicles uses for (minibuffer) completion help.

I think it's nuts that vanilla Emacs still uses ordinary, printing chars such as
`?' and `newline' for special minibuffer commands, instead of just inserting
them.  And even `SPC' outside of (finally!) file names.  A user is more likely
to expect `?' to self-insert than to think s?he should use `C-q ?' to insert a
`?'.

Yes, I know you've heard it before...  But glad to hear Eli in favor of `M-?'
here.
