The Stylus is ergonomically designed to work with your tablet for long periods of time. The user can switch between pen and finger entry without any manual mode switching. The stylus supports features such as palm rejection, hovering, and pressure sensing, which allow for accuracy and ease of use - with no calibration needed.
The two buttons are software-configurable for using features such as erasing, highlighting, or performing mouse clicks. 
You can use the tip of the stylus to draw shapes, select text, turn a page, and write, or sign the documents on your tablet. You can use the native Pen and Touch application in the Windows Control Panel: Control Panel > Devices > Pen
