RE: unhelpful menu keybinding notes

["Drew Adams" <drew.adams@oracle.com>]

    Alternatively, one could put explicit keyboard help strings into the
    menus (or have some property for that purpose on the function?).  One
    might assume that the people with actual "<cut>", "<paste>", "<copy>"
    keys would still try using them without being prompted for them.

Yes, this is a general problem with `substitute-command-keys', which we have
discussed before. Whenever there is more than one key sequence bound to a
command, the problem surfaces.

No matter what algorithm is used to choose (ASCII, non-ASCII, shortest,
longest, chords, non-chords, whatever), people will want to be able to
specify the binding to use in the result, and there is no way to do that
now. I hope we will address this after the release and find a good solution.

In my own libraries I sometimes hard-code explicit bindings and sometimes
rely upon \\[...]. The advantage of the former is that you can control what
gets communicated; the disadvantage is that that can be incorrect if the
user has changed the bindings.
