OK, try (require 'thingatpt) first. It is a useful thing even tho your code is perhaps (?) better in this case. > I like to flip a lot of characters in one > swell swoop. OK, you can use the C-u prefix to do that. So `C-c f' is 4^0 = 1, `C-u C-c f' is 4^1 = 4, `C-u C-u C-c f' is 4^2 = 16, and so on; and `C-u x C-c f' is x! This can be implemented like this: (require 'cl-macs) (defun flip-case (times) (interactive "p") (cl-dotimes (_ times) (let ((c (string-to-char (thing-at-point 'char t)))) (delete-char 1) (cond ((and (>= c ?A) (<= c ?Z)) (insert-char (downcase c))) ((and (>= c ?a) (<= c ?z)) (insert-char (upcase c))) (t (insert-char c)))) )) (global-set-key "\C-cf" #'flip-case) -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 42 Blogomatic articles -
