The $...$ construct is recognized by a regexp which, while complicated, is not complicated enough to recognize everything that's marked "punctuation" in the syntax tables. Look for org-latex-regexps in org.el (and note that the regexp for "$" is about twice as long as the next longest regexp - the one for "begin"). The others (for \(...\), \[...\] and $$..$$) are fairly trivial. > My questions: > > 1.
