How about another idea... would it be possible to remove "\$" as a math
delimiter? I *do* use $math$ a bit, at least in this document, and have
=TeX:t and LaTeX:t= in my options... thus, I'm very careful about prefixing
"\" to any instances of $ and %. Removing \$ as a math delimiter or making
"\" register as the "universal escape character" would also do the trick.

If I removed $ as you suggest, could I use \begin{math}/\end{math} inline?
I have quite a bit of inline math.


Thanks!
