    query-editor: Add a key binding to focus view
    
    We used to emit the "focus-view" in handle_event() when the [Down] and
    [Up] keys were pressed.
    
    But this doesn't work after the previous commit.
    
    To restore it's function, use the "focus-view" signal into a key
    binding signal.
