Re: Including tex commands in a list

[steve-humphreys]

Had made it as you suggested, but I think there has to be some changes
that have to be done in the regexp.

Have used

(defconst crucible-mtksy-keywords
`(;; Greek
   (,(rx "\\" word-start
      (or "alpha" "beta") ;add the other letters here
      word-end)
   (0 'crucible-mtksy-tfc))) )

In the expression (1 'crucible-mtksy-tfc), the "1" is an option to not
highlight the starting "\".
