Using the TrackPoint
The TrackPoint consists of a pointing stick and three click buttons. The pointing stick is used to control the cursor. The three click buttons are the left button, the right button, and the center button. This section provides information on using the pointing stick, configuring the center button, and customizing the TrackPoint.
Using the pointing stick
To use the pointing stick, do the following:
1.Place your hands at typing position, and press gently on the pointing stick in the direction that you want the pointer to move. You can press the pointing stick away from you to move it up, toward you to move it down, to one side or the other to move it sideways. The speed at which the pointer moves depends on the pressure you apply to the pointing stick.
Note: The cursor might periodically drift. Stop using the pointing stick for a few seconds and try again. The cursor will work normally.
2.To select and drag an item, stop the pointing stick and press the left or right button with your thumb. The left and right buttons function the same as the left and right buttons on a conventional mouse.
Replacing the pointing stick cap
The cap on top of the pointing stick is removable. You can use any of the cap types shipped with your notebook computer to replace your current cap.
To remove the cap on your pointing stick, simply grasp the top portion of the cap and pull it up.
