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.
