I believe you want to look at `TeX-electric-math' (https://www.gnu.org/software/auctex/manual/auctex/Quotes.html#index-TeX_002delectric_002dmath): --8<---------------cut here---------------start------------->8--- TeX-electric-math is a variable defined in ‘tex.el’. Its value is ("\\(" . "\\)") Original value was nil Local in buffer foo.tex; global value is nil If non-nil, when outside math mode ‘TeX-insert-dollar’ will insert symbols for opening and closing inline equation and put the point between them. If there is an active region, ‘TeX-insert-dollar’ will put around it symbols for opening and closing inline equation and keep the region active, with point after closing symbol. If you press ‘$’ again, you can toggle between inline equation, display equation, and no equation. If non-nil and point is inside math mode right between a couple of single dollars, pressing ‘$’ will insert another pair of dollar signs and leave the point between them. If nil, ‘TeX-insert-dollar’ will simply insert "$" at point, this is the default. If non-nil, this variable is a cons cell whose CAR is the string to insert before point, the CDR is the string to insert after point. You can choose between "$...$" and "\(...\)". Automatically becomes buffer-local when set. You can customize this variable. --8<---------------cut here---------------end--------------->8--- Bye, Mosè
