Mojo.Event.forward
From WebOS101
The forward Event is sent whenever the user does a forward swipe on the gesture area. Compare with Mojo.Event.back. The forward gesture has no defined default behavior in webOS applications so consider carefully what you will use it for. Some applications use it to bring up options on full-screen (immersive) apps, some (such as the browser) use it move forward and others use it to jump back to the main screen.
