Some notes about the usage of the above values:

• ''Misc'' and ''Serial'' are used for the tool serial numbers. The serial for the pad is -1.
• ''ToolPen'' and ''ToolRubber'' are the two indicators for pen or eraser (in X11 driver lingo), thus if ''ToolPen'' is set, the front end of the stylus is in proximity.
• ''Touch'' indicates if the current tool (pen/eraser) is touching the surface.
• ''ToolFinger'' is set whenever a button on the pad is pressed, and released with that button too.
• ''Stylus'' and ''Stylus2'' are the side buttons on the pen.

Example for Eraser usage, first proximity then touch:
