Re: position on changing defaults?

[Richard Stallman]

    I'm not sure I understand what you're proposing.
    One thing we can do right now is:

      (define-key function-key-map [S-up]
        (lambda (prompt) (setq foo-shited t) [up]))

It is rather kludgy to set `foo-shited' that way.
(And can you be sure it is reliably reset to nil?
What if you type C-g at the wrong moment?)

Why do this rather than directly bind S-up to a command
that does exactly what is wanted?
