4,442 PointsI just remembered, Command + Option + Return also opens the assistant editor. It's extremely useful in programming shaders for 3D graphics.

4,442 PointsThere's a weird bug in Xcode that prevents it from working all the time. I think you have to open a new tab to get it to work properly. I think there's an easier fix, but I can't remember it.
Also, Option + Click opens up the assistant editor to view things side-by-side, and Command + Return closes it.
