With the new version of Pages you can now create linked text boxes to make complex page layout documents. The linking system works differently than in older versions of Pages, using colors and numbers to denote which boxes link and in which order. You can flow text across multiple boxes, and also on multiple pages. This feature is also in the iOS version of Pages, but with a slightly different interface.
