It finds the regular expression that will match the given list of strings and I find your application smart. (regexp-opt '("something" "anything")) ⇒ "\\(?:\\(?:any\\|some\\)thing\\)" (regexp-opt '("TODO" "DONE" "DELEGATED")) ⇒ "\\(?:D\\(?:ELEGATED\\|ONE\\)\\|TODO\\)" and that may be reused with certainty to work: (highlight-regexp "\\(?:D\\(?:ELEGATED\\|ONE\\)\\|TODO\\)") -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
