WHATEVER YOU DO, DO NOT PUT "^0", "^1", ETC	IN A STRING FOR SUBSTITUTION UNLESS
YOU REALLY KNOW WHAT YOU ARE DOING!!!!!!

There, now I'll explain why.  It is very easy to cause an infinite recursion
inside the toolbox by trying to substitute like this.  I know, I did it once.
The strings you pass in get re-expanded, and then re-parsed to check for any
of the special sequences (e.g. "^0".)  This is a great feature, but you can
have problems with it.

I would suggest putting a very narrow blank character between the "^" and the
number.
