    messageTray: Add shortcuts to summary boxpointer
    
    Currently opening the summary boxpointer acts as a stop gap for
    keynav - the only shortcut still working is "Escape" to hide the
    tray altogether.
    Change the handling of Escape to only close the summary boxpointer
    and allow to use the down arrow as alternative (unless the boxpointer
    already processes the key press itself of course, like the chat
    entry does). Also add a Delete shortcut to dismiss the open summary
    item.
