Using The Touchpad - HP Compaq Presario,Presario V4000 Hardware And Software Manual

Using the TouchPad

In Windows the TouchPad provides the navigation, selection, and
scroll functions of an optional external mouse.
To move the pointer, slide your finger across the TouchPad
surface in the direction you want to move the pointer.
To execute the click functions of the left or right button on
an external mouse, press the left or right TouchPad button.
To scroll, slide your finger along a scroll zone in the direction
you want to scroll. Sliding your finger from the TouchPad
region to a scroll zone without first lifting your finger from
the TouchPad region will not activate the scrolling region.
The TouchPad is enabled when the notebook is turned on. If you
work with keystrokes rather than mouse actions, you may prefer
to disable the TouchPad to prevent accidental TouchPad activity.
