    appFolder: Don't block all shortcuts
    
    App folder popups take a grab when opened, and as we don't pass any
    particular pushModal() parameters, all keybindings are blocked. While
    this makes sense for most keybindings that would interfere with the
    popup interaction, others like volume/brightness keys or screenshots
    can be allowed safely.
