accidental light touches or taps on the touch pad may select an 
item or text on the screen, and potentially the item or text may 
be replaced by the next character you type.

There are two active regions on the touch pad that allow you to 
scroll as you would with any wheel device on a mouse or trackball.

To scroll vertically, run your finger up or down along the right edge 
of the touch pad. To scroll horizontally, run your finger along the 
bottom edge of the touch pad. This feature can be disabled or 
changed in the Mouse Properties dialog box.

When a step instructs you to click or choose an item, move the 
cursor to the item, then press and release the primary (left-hand) 
button. To double-click, press the primary button twice in rapid 
succession. The primary button usually corresponds to the left 
mouse button.

The function of the secondary (right-hand) button depends on the 
program you are using. It usually corresponds to the right mouse 
button (“right-clicking”). Check your program’s documentation to 
determine whether it uses the right mouse button.
