title: Does anyone know what the new Exit icon is used for when editing storyboards using Xcode 4.5?
body: <p>Right-clicking the Exit icon yields an empty window. Can't Ctrl-drag a connection to any IB elements or corresponding source files. Docs give no love. Doesn't appear in nib files, only storyboards. My assumption is that it's a corollary to segues, but I don't see any new methods to back it up. Anyone?</p>
