    legacyTray: Pass on keyboard events to the icon
    
    There is currently no way to trigger an icon's right-click menu by
    keyboard. While there's a good chance that the icon will ignore
    <shift>F10 and similar shortcuts, passing on key events will at
    least make it work for some icons ...
