Pen Usage
Your computer uses several input devices. The standard external USB keyboard and mouse are present, plus you can opt for the
electrostatic pen/stylus or use your finger as an input device.
Using the Pen as a 'Mouse'
You can use the pen the same way you use a mouse or touch pad with a laptop computer. Holding the pen near the display
makes a small cursor appear. Moving the pen moves the cursor. The following table describes how to use the pen.
Table 18. Pen functions
Action Function
Gently tap the pen tip on the screen Same as a single-click on a mouse.
Gently tap the pen tip twice in quick succession on the
screen. Same as a double-click on a mouse.
Touch the pen on the screen and hold it in place momentarily
until Windows draws a complete circle around the cursor. Same as a right-click on a mouse.
Using the Pen as a Pen
The handwriting recognition software makes it easy to enter text into your applications with the pen. Some applications, such as
Windows Journal, allow you to write with the pen directly into the application window.
