I have Kubuntu Dapper (i.e., a debian variant), emacs 21.4.1, axiom wh-sandbox
(very recent)

Cliff, I think it would be best if you start hacking!  Most likely, emacs
people will be able to help, but there are simply too few axiom people around!

Just another idea: M-up could get you into output "mode", and in that "mode",
some ordinary keys have a different meaning: b for blue foreground, B for blue
background, g for green, r for red, space for black, etc.  That would really be
a killer app!  None of the current interfaces for maple, mathematica, mupad,
etc. is able to do that!  I beg you to look at it!

I think you shouldn't go further with the notebook idea.  It's cute that
invalid input turns red (unfortunately undo (M-_) doesn't turn it black
anymore), but I'd really leave it at that.

Forget about automatically determining boundaries.  And for the moment, region
and line would be just wonderful.

Well, just get over it :-) Don't try to make it perfect! Yes it should work,
but for the moment, it's more important to make life with axiom more comfy.

but I am!  Only, I think my abilities would be rather badly employed by trying
to mess with emacs modes.

Again, many thanks,
