1.4.2 Glidepad Pointing Device

All members of the Extensa 57x family feature a built-in glidepad pointing

device located near the center of the keyboard’s palmrest. With light finger

pressure, the cursor can quickly be positioned to the desired point; a quick

double tap on the glidepad and you have selected an object. Two sele ct

buttons (switches) are located along the front edge of the notebook for use in

the traditional select/drag features of a mouse device.
