Yes, that's what I thought: org-inside-LaTeX-fragment-p' is the key.

On purpose, Org won't insert a footnote inside a LaTeX fragment.  But,
in your example, it is fooled by the currency.

One workaround would be to remove "$" as a math delimiter from `org-format-latex-options'. 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!
John
