The default value for :matches is ("begin" "$1" "$" "$$" "\\(" "\\["). It looks like the value hasn't been touched in a long time, and that AFAICT the "begin" should cover "align" just as it covers "equation". And I'm not spotting any recent changes on Org's end that should affect this. > My test-file.org: > ----8<---------8<---------8<---------8<----- > > * blabla > \begin{equation} > \label{eq:1} \frac{}{} > test_{cds} \frac{}{} > \end{equation} > > \begin{align} > \label{eq:2} > test$_d$ fr > \end{align} > > $\frac{}{} fds_{fdsf} \frac{}{}$ > > \begin{align*} > fr > \end{align*} > > > ----8<---------8<---------8<---------8<----- > > - detection works for: \begin{equation}, $$, \[\] (not in testfile) > - detection does not work for: \begin{align}, begin{align*}; subscript _ > does insert extra $_{}$, which it should not in math mode, and fr does > not get expanded to \frac{}{} > > Emacs : GNU Emacs 26.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20) > of 2020-05-19 > Package: Org mode version 9.3.7 (9.3.7-13-ge62ca4-elpaplus @ > /home/stefi/.emacs.d/elpa/org-plus-contrib-20200713/) On master, maint, and the commit matching your reported version (e62ca4), I tried org-inside-LaTeX-fragment-p within each block of your test file, and it returns non-nil, including in the align and align* blocks. So I dunno... Could some org-cdlatex users out there give the test file a try?
