commit 7b2be5c529252ae1485290405c1ac8d6551c8c20

    app: add Alt-click on visibility and locks for exclusive switch within…
    
    … the selected items only.
    This is the exact same algorithm as Shift-click, except that Shift-click
    switch exclusivity within the whole level of items. Alt-click does the
    same but only within selected items in the list.
