Hi Carsten, Just to add to the discussion, transient-mark-mode is off for me in GNU Emacs 22.2.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2008-11-09 on raven, modified by Debian.
If I start with emacs -q transient-mark-mode is nil. I've explicitly set it on in my .emacs (as of the beginning of this discussion) and that makes things work better for me. ,----[ end of my .emacs ] | (transient-mark-mode 1) `---- Regards, Bernt Carsten Dominik <domi...@science.uva.nl> writes: > Dear Robert, > > also region-active-p requires transient-mark-mode to be active, if you > look > at the definition of the region-active-p function, you will see that. > > transient-mark-mode is on by default in Emacs.
