Oh, right -- it's transient mark mode that does this stuff? That is, if you run a command that inserts something in the buffer, then it'll switch the region off? So `save-mark-and-excursion' works exactly as it should. But if you don't want transient-mark-mode to switch itself off, you have to say something like: (defun my-test-func () "Test if save-mark-and-excursion is working." (interactive) (save-mark-and-excursion (goto-char (point-min)) (with-silent-modifications (add-face-text-property (point) (1+ (point)) (list :background "orange"))))) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
