RE: Help buffer key bindings

[Drew Adams]

        Bind "l" to help-go-back in help-mode, to make it behave a tiny bit
        more like info mode.

        (add-hook 'help-mode-hook (lambda () (define-key help-mode-map "l"
        'help-go-back)))

    Maybe binding "l" to help-go-back is a good thing?

And bind it to the other keys that `Info-history-back' is bound to -
including `mouse-4'.

Actually, I'm not sure that `Info-history-back' ever got bound to `mouse-4'.
IMO, it should - `Info-history-back' should be bound to all of the usual
things that `Back' is bound to in a Web browser (unless those bindings are
already taken).

Like Web pages, Info is a thing that people can browse with the mouse
(without the keyboard) - and many people will use it that way. Of those who
do, many will have 4- or 5-button mice, and will expect `mouse-4' to go back
to previously visited pages (nodes).
