Using the UltraNav pointing device

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

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

•Set the TrackPoint 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 while limiting the use of the touch pad to scrolling, tap zones, and slow-motion pointer functions.

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

This setting enables the use of all basic and extended functions with the touch pad while limiting the use of the TrackPoint to scrolling and Magnifying Glass functions.

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

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

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.
