    Full Screen window won’t get any keyboard events the way it is, due to the fact that it was created with with the NSBorderlessWindowMask style mask. Apparently windows of this type can’t become “key windows”. However, you can fix this problem by subclassing NSWindow and overriding the canBecomeKeyWindow method.

    - (BOOL)canBecomeKeyWindow
    {
        return YES;
    }
