When I set the preview mode to selectable the app is restarted at the home screen. However, I want really to look at a secondary screen reached by clicking a navigation link icon on the main screen. In this mode clicking the icon selects it but doesn't activate it. This seems like a catch 22. How could I get to the secondary screen in selectable mode? Is there a key/click combination that does a real click in selectable mode so I can get to it?
