Is there a way to cycle through open windows. I quite often use this when I want to reference something in another file. On windows this would typically be Ctrl + Tab, but I can't find a way to do this in Xcode on a Mac.
On a Mac you can cycle through any program's windows using Cmd + ` (backtick)
On Xcode4 same command is achieved with Cmd + Ctrl + ↑/↓.
