    higherorder: Extra actions for triggers and similar
    
    We start with an action "Select in Kupfer": it only makes sense in
    Triggers or delayed commands. With it, you can make a trigger to
    show Kupfer, with a particular object selected. It is much like the
    "magic keybinding" for current selection, but for any object.
