    viewSelector: Avoid stealing focus from other entries into overview entry
    
    The captured-event handler just redirects focus there on the first keypress,
    what it doesn't account for is that other entries may be active while the
    Activities overview is opened (eg. alt-f2, or other modal dialogs). Play
    along with other entries, and make it only steal focus if no other entry
    is selected.
