This is all correct I think (except for the ominous first
sentence). But having
(setq major-mode 'org-mode)
in one's .emacs should not have any effect: major-mode is
buffer local, so the setting above should not have any
effect on *anything*, afaict. To make org-mode the
default mode for new buffers, you'd have to say
(setq-default major-mode 'org-mode)
I've added each of those to my minimal .emacs and I have
no problem using S-{right,left} to change the TODO state
in a .org file. When I set org-mode to be the default
major mode and I open an unrelated file, its major mode
is set to org-mode, but when I S-{right,left} at some
arbitrary place, I get a message:
To use shift-selection with Org-mode, customize
`org-support-shift-select'
and the corresponding message in the *Messages* buffer
is:
if: To use shift-selection with Org-mode, customize
`org-support-shift-select'
That's an error, but it's a "reasonable" error: not right
but not too bad.
And when I ``find-file foo.bar'' which would normally
open it in fundamental mode, I do get it in org-mode and
everything works as it should: I can add headlines and
change TODO states normally.
So to summarize: no idea why that setting should have any
effect at all.
Nick
PS. The only possible explanation I can think of is
version differences:
Org-mode version 7.7 (release_7.7.205.gce02a)
GNU Emacs 24.0.50.1 (x86_64-unknown-linux-gnu, GTK+
Version 2.22.0) of 2011-07-30
I have not tried with emacs 23.
