You can take off the pointing device cover and replace it with the additional 
cover supplied with your computer.

Right-click

Press the right button once. In many applications, this action 
displays a shortcut menu of context-sensitive choices.

Drag

Press the pointing device in a direction to place the pointer on an 
item or object. While holding the left button, press the pointing 
device in a direction, and then release it at the desired point.

Scroll

Press the pointing device while pressing the center button.

✍

The scroll function is available only with applications that support a scroll pointing device 
feature. Pressing the pointing device too hard may damage it.

✍

Make sure the cover is tightly secured to prevent damage to the screen when you 
close the computer.
