I can reproduce this, but I'm not quite sure what's going on. I tweaked your function: (defun my-test-func () "Test if save-mark-and-excursion is working." (interactive) (save-mark-and-excursion (goto-char (point-min)) (add-face-text-property (point) (1+ (point)) (list :background "orange"))) (message "%s" mark-active)) This messages t -- but evaling mark-active afterwards shows that it's nil. So something is deactivating the mark after the command has run, apparently? Hm... this sounds vaguely familiar to me... Anybody know what could be going on here? --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
