I made a few small modifications to my dedollar python script so that it will find all i contained in math delimited by either $...$ or $$...$$ and replace by k as long as they are not part of a control sequence. You are probably best off handling other display math environments manually, as you could end up modifying environment names and text embedded within the displays on a wholesale basis.

Howdy,

I was pretty sure it would require the use of a program/filter rather than a regex.

I'd guess that there are lots of align and align* environments, etc., which would complicate matters even more. But George hasn't said anything.

Good Luck,
