I would like to prettify \(A_i\) to Ai. Is this possible? I looked up the source of org-match-substring-regexp and tried to modify it, but no luck. any help?

  • org-cdlatex does that. But, maybe that is not what you want. – Tobias Jan 19 '16 at 14:59
  • There's tons of prettification modes, one of them even made it into Emacs! – wasamasa Jan 19 '16 at 16:18
  • Note that prettify-symbols-mode can only prettify symbols (strings, actually) to a single character (see doc of variable prettify-symbols-alist). So you would need to find a character for A_i. I don't know about other prettification modes. – JeanPierre Jan 19 '16 at 17:57
