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:
