Your computer comes with the UltraNav pointing device. The UltraNav pointing device consists of the TrackPoint pointing device and the touch pad, each of which is itself a pointing device with both basic and extended functions. You can configure both devices by choosing the settings you prefer as follows:

•Set both the TrackPoint pointing device and the touch pad as pointing devices.

This setting enables the use of all the basic and extended functions of the TrackPoint pointing device and the touch pad.

•Set the TrackPoint pointing device as the main pointing device and the touch pad for extended functions only.

This setting enables the use of all basic and extended functions with the TrackPoint pointing device while limiting the use of the touch pad to scrolling, tap zones, and slow-motion pointer functions.

•Set the TrackPoint pointing device as the main pointing device, and disable the touch pad.

•Set the touch pad as the main pointing device, and disable the TrackPoint pointing device.

Changing the UltraNav pointing device settings

To change your UltraNav pointing device settings, go to Control Panel and click Hardware and Sound ➙ Mouse ➙ UltraNav. Then change the settings as desired.

Using the TrackPoint pointing device

The TrackPoint pointing device consists of a pointing stick 1 on the keyboard and three click buttons at the bottom of the keyboard. To move the pointer 5 on the screen, you apply pressure to the nonslip cap on the pointing stick in any direction parallel to the keyboard; the pointing stick itself does not move. The speed at which the pointer moves depends on the pressure you apply to the pointing stick. The functions of the left 4 and right 2 click buttons correspond to those of the left and right mouse buttons on a conventional mouse.

The TrackPoint center button 3 , called the scroll bar, enables you to scroll Web pages or documents in any direction with no need to use the graphic scroll bars on the side of the window.
