I think I have to agree here with Lennart.  If a user expects shifted
cursor motion to do selection, a variable reaction of Emacs depending
on context will be confusing.

For me this issue is that s-cursor commands do very valuable and
intuitive stuff in Org, and these commands are heavily advertised
in the manual and likely used by a large number of active users, who
would also be confused if we suddenly changed this behavior.

In addition to that, Emacs's has alternative methods for
creating a selection that are far superior in my mind.  Setting
the mark and then moving the cursor by any means, in
particular also search ans jumping to the beginning/end
of the buffer - I miss this so much in any program outside Emacs.

I therefore think it is the right decision to have a variable for
setting this and my personal preference would be to let me have my
current default setting in Org-mode which allows me to use these
valuable keys.

After all, it is Emacs 23 that changes its default for these keys
from what we were used to, not Org.
