I think it's as useful as the other key bindings we show there.  This
doesn't annoy me, and I sometimes find it useful.

There's no reason to believe that people remember all the menu items
by heart, no more than we expect them to remember key sequences.  I'm
sure that if you look at the menu bindings, you will sometimes find
items there you didn't know about, or knew but forgot.

This is a serious change in behavior, so I think it could only fly as
an opt-in feature.  It sounds like a personal preference, so an
option, off by default, for it sounds about right.

Thanks.
