Ah, yes. I did add that to my .emacs...

Ok... So SLIME doesn't interact with that in any way, I guess?

This is great! I'm using it now, and it already helps with some symbols
that I define which start with "do-".

But I was thinking that maybe SLIME could dynamically add keywords to
be highlighted?

Like, whenever SLIME saw a (defmacro foo ...), it would add "foo" to the
keyword list? That would be wonderful!

Thanks!
