How can I enable vertical split views in the Xcode IDE?

Question

Hello. I'm diving into iOS development and I'm using Xcode on a multi-monitor setup. Obviously I want to take advantage of the multiple monitors to view and edit multiple panes of source code, but I'm having a hard time figuring out how to enable vertical split views. In other IDEs, it's just an option you click in the "Window" menu. How do I enable vertical split views in Xcode?

Thanks so much in advance!

Hold down alt and click the little tiny box (with a horizontal line through it) in the upper-right-hand corner of the screen. It's underneath the tiny little lock icon.
