The View Window is a second Image window that shows users specific Named Views in your project and/or alternate views.
This window is activated by clicking CTRL + 2 or selecting View>View Window. Also, by default, the View Window will launch when you access a Named View via a Hot Link. See Using Hot Links and Named Views for more information.
From the drop down lists you can select a page (above) of your plan, or, a named view (below).
