Hi Arash,

Thanks, sounds good.  I'll plan to send these commands as a separate bug
(and have no further comments on the current bug).  Some responses:

>> ;;;###autoload

>>   "Convert LaTeX equation environment at point to inlined math.

It will indeed break (i.e., put the \label{...} inside the $...$) if the
\label{...} does not occur on the same line as \begin{...}.  Perhaps we
could kill any labels first.

A related issue is ampersands alignment characters (e.g., in align
environments) that should not exist when we convert to inline, but
ampersands occur in other ways (e.g., matrices), so it seems tricky to
get this right.  Personally, I use the command only when the displayed
expression is simple enough, which restricts the possible edge cases.

Thanks, best,

Paul
