This brings me to something I have thought about a couple of times, namely what is the right way to write the interactive specification of a function that reads argument(s) from the minibuffer, AND, if available, act on the region as well? (defun do-a-on-b (a b &optional start stop) (interactive ;; check (use-region-p) (list ;; ask for a ;; ask for b start stop) ;; ... ) ;; ... ;; do it ) ? -- underground experts united http://user.it.uu.se/~embe8573
