Using The Glide Pad
Your computer is equipped with an integrated pointing device called a glide pad.
Using the glide pad, you can move the pointer, select an item from a menu, and
perform other tasks in the same way you would with a mouse.
Do not hit or scratch the surface of the glide pad with pointed objects
2
Using the Glide Pad
Take a moment to become familiar with how the glide pad works.
•
(such as a ballpoint pen).
Do not operate the glide pad with a moist finger. This may cause the
•
glide pad to operate incorrectly.
Place Your Fingertip
Place your left or right hand next to the glide pad, resting your wrist naturally in a
relaxed manner. Place your thumb or finger on the glide pad.
Move Your Fingertip
The rectangul ar pad of the gli de pad acts l i ke a miniature duplicate of the disp l ay.
As you slide your fingertip across the pad, the pointer on the screen moves in the
same direction across the screen. The glide pad is very sensitive, so you do not have
to exert much pressure on the pad. The glide pad will respond to a light touch from
your fingertip.
2-4
Click, Double-click, and Right-click
To click or double-click, you can use the left button just like that of a mouse.
Instead of clicking the left button, you can also just tap gently anywhere on the
rectangular pad. For right-clicking, you can use the right button or tap the pad with
three fingers.
Drag and Drop
You can move icons or windows by using “drag and drop” below:
1. Position the pointer over the object.
2. Press the left button; do not release it.
3. Holding down the button, move the pointer. The object moves together with the
pointer.
4. Release the button when the object reaches its destination.
Scroll
You can scrol l through informatio n in a list or in a document by using the glide pad.
To view information vertically, place your finger on the most right part of the glide
pad and slide your finger up and down. To view information horizontally, place your
finger on the bottom part of the glide pad and slide your finger left or right. This
procedure works in limited applications. See Windows help for more information.
