Is there a way to disable the Alt-O shortcut for invoking the 'Log out' action? We use web server authentication for our mediawiki on our intranet so there is rarely a need for logging out. Also, people accidentally hit Alt-O when they mean to press Alt-P to preview, so I'd like to disable the shortcut. I don't want to completely disable logging out; it is useful for some to logout and then log in under a different administrator account. (I will edit MediaWiki:Tooltip-logout to remove the Alt-O hint).
