[Down arrow]+[Selected note]
[Cmd]+[Opt]+[Down arrow]+[Selected note]
[Double-click]+[viewport part of containers and agents]
Same action as Focus view, and logical opposite of Expand View. Acts like a 'Down Arrow' for Map views. Only works if a note has active focus. There is no menu reference to this shortcut.
All map shortcuts work even if a container has its viewport hidden by expanding the title area.
