Using the TrackPoint III
Operating with the TrackPoint III
Note:
No other software is required for the
TrackPoint III; it works with the
PS/2 mouse driver.
The keyboard contains a unique cursor-pointing device called the
TrackPoint III. Pointing, selecting, and dragging all become part of
a single process, without moving your fingers from their typing
position.
The TrackPoint III consists of a stick
1
on the keyboard and a pair
of click buttons
2
below the keyboard. The motion of the cursor
on the screen is controlled by the amount of pressure applied to the
nonslip cap stick in any direction parallel to the keyboard; the stick
does
not move. The speed at which the cursor moves corresponds
to the amount of pressure on the stick. The function of the click
buttons depends on the software that is used.
