What is Power Scroll? How do I Power Scroll?
Power Scroll is a two-finger gesture introduced by Carbon team for jumping to the top or bottom of any given screen/timeline.
Simply all you have to do is flick up or down using two fingers and you'll get to either top or bottom of the screen or timeline that you're viewing. Simple as that.
You'll find Power Scroll supported on many apps on webOS after we introduced it, yep, you got it first on Carbon.
