Tap twice and you can switch your tool in the Notes app from a pencil to an eraser. The gesture controls are also customizable, allowing you to create shortcuts to difference functions.  > The second-generation Apple Pencil also attaches magnetically to the side of Apple's newest iPad Pro and pairs automatically. And instead of charging via a Lightning connector, it has a new method that allows the pencil to charge wirelessly when docked to the iPad Pro.
