When I run revert-buffer in emacs it says:
You can run the command `revert-buffer' with s-u
I've never seen any keybinding beginning with s- before. What key is that?
My emacs version is GNU Emacs 23.2.1 (x86_64-apple-darwin, NS apple-appkit-1038.29) of 2010-05-08 on black.local
Update: Now I see why I didn't understand
s-u. It is something added by aquaemacs. The first thing I did after installing aquaemacs was
(setq mac-command-modifier 'meta) to make it work the way I expect.
