[Orgmode] Re: question about org-region-active-p
Hi Robert,
I have added documentation in the places you suggested. Also, I added
a remark in the Activation section.
Thanks.

Attached please find a patch file that gives a proposed set of
additions
to the manual on this topic, for your review. Interestingly enough,
there was already an index entry for transient mark mode at the html
export commands page.
Best,

[Orgmode] Re: question about org-region-active-p
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.

I am still inclined to think that this case is one where the user should get some warning because it's in that bad class of bug-like situations where code quietly does something that the user does not expect and that contradicts the documentation.

It's not an error to call org-region-active-p without transient-mark-mode; indeed some libraries turn this on and off, and the user is entitled not to use it.

I would suggest a modification to the manual and will submit one, but need clarification about one issue: the use of t-m-m seems to be a fallback for older emacsen that don't have region-active-p.
