Interface Builder. How do I toggle between open projects using a keyboard shortcut?

Question

Can someone please remind me how do I toggle between open projects using a keyboard shortcut? I briefly knew how to do this but it has evaporated from my brain and Google is no help.

Answer 1

I don't know what the shortcut is for switching between open projects, but in OS X in general you can use Command+` (backtick) to cycle among windows of an application.
