Touch Pad and Track Stick
Cursor Pointing Devices
Your computer it equipped with a Personal System/2 (PS/2)-compatible touch pad that provides full mouse functionality. A set of left and right
buttons, located below the touch pad, operate like the left and right buttons on a mouse. You can also perform many pointing functions by tapping
the touch pad, which is positioned for both left- and right-handed users. Click-and-drag buttonless functions are also supported.
An optional Dell™ DualPoint™ integrated pointing device is available, which provides a track stick in addition to the PS/2-compatible touch pad.
The DualPoint option also includes a second set of left and right buttons, located above the touch pad (see
Figure 5 and Figure 6 ). The track stick
controls the cursor on the display screen and is positioned in the keyboard to allow you to move the cursor while keeping your fingers in a typing
position. You can also perform many pointing functions by tapping the track stick. Click-and-drag buttonless functions are also supported.
DualPoint integrated pointing device software allows you to set the default for the type of cursor pointing device you want to use, as well as
sensitivity, motion, and drag-and-drop features of both the touch pad and the track stick.
Using the Touch Pad
The PS/2 touch pad detects the position of your finger over a touch- sensitive area to position the cursor within the display screen. The touch pad
provides the computer with full mouse functionality. The touch pad ’s two buttons, located directly below the touch pad, correspond to the left and
right buttons on a standard mouse.
