One option is to avoid such characters from file names. If there is a simple way of applying the bindings only in math mode, though, then I could implement that.

Howdy,

As an aside, there seems to be too many ways to enter math mode to be able to tell if you are there. E.g., $ or $$ (which, unfortunately also end math mode), \( or \[, or \begin{equation} or \begin{align}, etc., etc., etc.

Good Luck,
