Keyboard Shortcut for Notification Center not working The keyboard shortcut "Show Notification Center" you can set under System Preferences -> Keyboard -> Mission Control stopped working for me after a restart. 

I tried resetting to defaults, changing the short cut and finally exiting all running apps and processes - nothing seems to bring back the short cut.

Does anybody know how to debug this or a plist where I can manually edit this?
