Because comments in `message-mode' are inserted and interacted with the same way comments in programming modes, I thought the downmost code would work. But it doesn't; perhaps the "syntax" of a message hasn't been added to, or is incompatible with, the workings of `syntax-ppss'. Anyway, what about this? (defun point-in-quotation-p () (save-excursion (beginning-of-line) (string= ">" (thing-at-point 'char t)))) You can use `comment-start' if you don't want to hard-code the ">". Here is the code that didn't work - perhaps some of it can be brought over to the above code tho, in particular the interactive stuff. (defun point-in-comment-p (&optional print-message) (interactive "p") "True iff point is in a comment." (let*((comment (nth 8 (syntax-ppss))) (feedback (format "%s comment" (if comment "Yes:" "No"))) ) (prog1 comment (when print-message (message feedback)) ))) -- underground experts united http://user.it.uu.se/~embe8573
