Oh, no, not again :) But wait... if it happens again and again, _I_ don't have to do it again! "if anything can start anew, then everything must continue" So yes, here is an example: Note: The keywords don't have to be expressions BTW. They can be single words. Then, instead of the index (1 in the example) just add a dot, i.e. (word . face) \alpha^{high} \beta_{low} (progn (font-lock-add-keywords 'emacs-lisp-mode '( ("\\^{\\([[:alnum:]]*\\)}" 1 font-lock-builtin-face) ("_{\\([[:alnum:]]*\\)}" 1 font-lock-function-name-face) ) t) (text-mode) (emacs-lisp-mode) ) ;; ^ eval You can see the result in this screenshot: https://dataswamp.org/~incal/figures/emacs/high-low.png -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
