Re: Shift Tab should move backward in help buffers

["Richard M. Stallman" <rms@gnu.org>]

    The code which sets up the escape mappings for those terminals could
    set up an explicit direct mapping for "escape-sequence -> backtab"
    (bypassing the S-tab step) couldn't they?

I think so.  In effect, this would mean deciding that Emacs should
always deal with backtab, never with S-tab.  (We would want
function-key-map to map S-tab into backtab also, to ensure that this
is true even on systems that produce S-tab directly.)

That could be part of the solution to this problem.

That is true, but we'd just tell the users that nowadays they
should bind backtab because Emacs no longer uses S-tab.
