       I don't think CLIM can reliably detect when you ask for an activation
       character that is the same as an IE command binding, because IE command
       bindings are potentially per-stream and activation gestures are not
       associated with a stream (which you could claim is a problem in itself).

    Good problem!  I'm going to ignore it for now.

I think I'll probably ignore it indefinitely, since it involves an
incompatible change to the macro.  Grr.  Oh well, it's been with us
since Dynamic Windows, so I bet that it will never cause any bugs.

       I agree that the current behavior is undesirable, but I'm not sure
       exactly what to do about it.  I suspect that the proper thing to do is
       for LOOKUP-INPUT-EDITOR-COMMAND to exit immediately if it finds a
       character that is an activation or "blip" char, and simply not bother
       trying to find an IE command for those.  Does that sound agreeable to
       everyone concerned?

    As I said, the input editor already does check for activation
    characters (see code excerpt from input-editor.lisp below) and doesn't
    even call lookup-input-editor-command if it finds one.  Is this a
    local fix or something?

No, I think that Paul Weineke made this fix and sent it to me.  I
installed it and forgot about it.  But this is fixed in CLIM 2.0.

    (defmethod interactive-stream-process-gesture ((istream interactive-stream-mixin) gesture type)
      (with-slots (numeric-argument last-command-type command-state) istream
	(cond ((characterp gesture)
	       ;; The COMMAND-STATE slot holds the current IE command aarray,
	       ;; and gets updated when we see a prefix characters (e.g., ESC)
	       (when (char= gesture #\return) (setq gesture #\newline))
	       (let ((command (unless (activation-character-p gesture)
				(lookup-input-editor-command gesture command-state))))
		 (cond ((numberp command)
			(cond ((null numeric-argument)
	    . . .)))))))))
