Subject: bug#14945: 24.3.50; (elisp) `The Mark': mention that mouse selection turns on `transient-mark-mode' temporarily
Date: Wed, 24 Jul 2013 07:41:14 -0700 (PDT) [thread overview]
Message-ID: <34e84b3b-2268-4430-8bdc-f8cc67e68c3f@default> (raw)
The doc says nothing about selection with the mouse activating the
region and turning on `transient-mark-mode' temporarily. But it
does so.
emacs -Q
In *scratch* type this:
transient-mark-mode
(region-active-p)
mark-active
M-: transient-mark-mode ; to turn it off - verify with C-h v.
Put cursor after each of the sexps and hit C-x C-e. Now select each one
using only the mouse and use C-x C-e again for each.
Selecting with the mouse turns on `transient-mark-mode', at least
temporarily - the non-nil value is `(only)'.
Lisp users should be informed about this. For one thing, they will not
otherwise understand certain code, including `region-active-p', wrt
mouse selection.
