Thanks a lot. That's helpful and much info in this thread.
possibly begging, is it possible to get this to work with using font-
lock-keywords?
Here's what i have now based on all the info in this thread. I
couldn't see where it went wrong.
; Sin[x]^2 + Cos[y]^2 = 1
; π^2/6 == Sum[1/x^2,{x,1,∞}]
(setq myKeywordsLevel1
(quote
(
("Sin\\|Cos" . font-lock-function-name-face)
("π\\|∞" . font-lock-constant-face)
("x\\|y" . font-lock-variable-name-face)
)
)
)
(setq font-lock-keywords
(
myKeywordsLevel1
nil
nil
)
)
(font-lock-fontify-buffer)
In the “setq font-lock-keywords”, block, i tried various quoting and
nesting but no go.
