Touch Pad: Dell™Latitude™L400User'sGuide
Using the Touch Pad
The touch pad (see Figure 1) detects the position of your finger over a touch-sensitive area and provides the computer full mouse functionality. The
touch pad’s two buttons correspond to the left and right buttons on a standard mouse.

To best use the touch pad, follow these techniques:

motion, leave your finger on the touch pad and move the selected object by sliding your finger across the surface.
