I'm in LaTeX/PS mode and whenever I close my $ math statements the cursor jumps to the first $ and back to the closing $. How can I disable this?

I assume that you are using AUCTeX. According to the documentation of TeX-insert-dollar among other things the following happens if you input the closing $ sign:

Show matching dollar sign if this dollar sign ends the TeX math mode and ‘blink-matching-paren’ is non-nil.

What you can do is to set blink-matching-paren to nil.

EDIT: This will also affect the behaviour of emacs when you input a closing parenthesis etc., but you can use other modes e.g. show-paren-mode to still highlight the opening parenthesis.

  • Yes, I'm using AUCTeX. What is supposed to happen for closing parenthesis? I don't think I see anything happen. Commented Apr 6, 2019 at 20:03

    For parentesis I see the same behaviour that you describe for $, i.e. from ) the cursor jumps to ( if blink-matching-paren is set to t. But if you don't like this behaviour anyway then this should be fine.

  • I see the first parenthesis gets highlighted when closing, but it doesn't make my cursor jump back and fourth like with $. Is it because I am using emacs evil mode? blink-matching-paren is set to t Commented Apr 6, 2019 at 20:11

    You are right! There is no jumping of the cursor but only highlighting. Maybe you have (as do I) the show-paren-mode activated. Without that and blink-matching-paren set to nil there is no highlighting on my system.
