The display has a touchscreen used to activate programs in Windows
CE and to make selections. The touchscreen works similar to a mouse.
Two styli are provided: a small onboard stylus that snaps into a holding
bay built into the top of the case and a full size pen-type stylus. Other
pointed objects can be used, including a finger. Take care not to use a
device that will scratch the screen.
Calibration
To calibrate the touchscreen and set up the screen-tap sensitivity, refer
to Windows CE, Control Panel, Stylus later in this section. If you have

- Touch the screen at the desired location, much as you would point

- Drag and drop items by touching and holding the item on the screen,
dragging the stylus to the desired location, and removing the pointing
