    I've been having some peculiar behavior in Lucid Clim 1.0 with keyboard
    accellerators for commands.  If my command definer looks like:

    (define-cyc-listener-command (com-show-u :name t :keystroke #\control-g)
	()
      (accept-and-show-unit))

    Then the keystroke I have to type is #\control-G, not #\control-g

    Has anyone else seen this?  Its happened for me on both DEC 5000s and
    Sparc2s. The same code works ok on Genera.

On Genera the reader ignores case, so both #\control-G and #\control-g
read as the same characters, which is the character that corresponds to
typing G with the Control key held down.  #\control-shift-G corresponds
to typing G with both the Control and Shift keys held down.

I believe that the Lucid reader pays attention to case inside of #\, so
if you want to create an accelerator that corresponds to typing the G
key with the Control key held down, you should specify #\control-\g
(note the backslash before the "g").
