I'm finally starting to get over my initial frustrations with Xcode 4.0 (why on earth did they think changing all of the keyboard shortcuts was a good idea).
However, one simple task is beyond me right now... how do I switch between multiple open projects via the keyboard?
For example, I have two different Xcode projects open, and the mac will put them both into the same Xcode application (unlike Windows where you can easily see multiple instances of the same application open). I want to quickly toggle back and forth between these projects without going to Window -> (choose the other project). Is there an easy keyboard shortcut for this? It seems that there used to be.
