Hi Kyle, hi mailing list,
I also evaluated (org-inside-LaTeX-fragment-p) and got non-nil values
for all blocks, however, inside the align* environment, the "fr" does
not get expanded on TAB whereas it does in equation environment. So
either the matchers do not include align/align*, or there is something
different now with cdlatex.
Btw, this is what I got from evaluation:
(#("\\begin{align*} 0 14 (fontified t line-prefix #(" " 0 4 ...)
wrap-prefix # (" " 0 4 ...))) . 15791)
and
(#("\\begin{equation} 0 16 (fontified t line-prefix #(" " 0 4 ...)
wrap-prefix # (" " 0 4 ...))) . 15824)
Does someone know how to find and configure the matchers?
I am pretty sure it worked before with align* environment, as I am using
it all the time :)
regards
