Using the Pointing Stick (Pointing Stick Models)

The pointing stick performs the same basic operations as a
mouse. It functions with any software that supports a
Microsoft-compatible mouse.
The pointing stick keyboard includes the pointing stick 1, left
pointing-stick button 2, scroll pointing-stick button 3, and right
pointing-stick button 4. To operate the pointing stick, press on
the pointing stick with your index finger in the direction you want
to move the cursor and click the left or right button to make a
selection or complete an activity. You can also use the pointing
stick to scroll. While pressing on the pointing stick in the
direction you want to scroll, hold down the scroll button.
