Is there any buttons in the pen, if not, is it possible to incorporate a "button" into a passive pen (no battery etc)? How's single click separated from double click and what about right clicks on the mouse, you have to push the pen twice against the screen
or what? I'd imagine the pen could have a area which is pressure sensitive, functioning as a button.
There are several functions that can be configured for the pen. Holding the pen rather than tapping on a highlighted area will act as a right click as will a double tap.
The button can also be configured to be used as right click, or several other commands. Some pens have more than one button that are configurable as well.
