Thanks, I like the idea.  I tried it, and it seems useful.

But I have one concern.  Is there anything else we could use those
keys for?  For example, what about navigating sections in the file, or
even (next|previous)-line?

Let's say we introduce a "foldable" help buffer, such that minor mode
documentation would be collapsed by default.  (Sorry, I can't find the
feature request now, but it's in the bug tracker somewhere.)

Will this key binding still be the one we want?

I think we should do this on master to let people test the change and
get used to it.  Maybe we will want to change it before release.
