A Pro Pen is included when the Surface Pro 2 is purchased, but an extra one can be bought separately as a spare. The Pro Pen allows Surface Pro 2 users to take notes and draw within apps; the pen can also be used as a mouse.
The Pro Pen features a pressure sensitive tip. The thickness of writings and drawings made using the pen varies depending on the amount of pressure applied. It also features a pen button that is used to access quick menus and an eraser that deletes pen strokes and flicks, which are swift pen strokes used to perform shortcuts and navigate the Surface Pro 2.
