Using and Configuring the Trackpad

Configuring and using the trackpad is straightforward. You use the Keyboard & Mouse pane of the System Preferences application to control how your trackpad works. When you are using a mobile Mac, the Trackpad tab becomes available. Follow these steps:

1.	Open the Keyboard & Mouse pane of the System Preferences application and click the Trackpad tab (see Figure 12.5). Figure 12.5. When you are running Mac OS X on a mobile Mac, you can set the trackpad options using the Trackpad tab on the Keyboard & Mouse pane.
2.	Use the Tracking Speed slider to set the speed at which the pointer moves relative to your finger's speed on the pad.
3.	Use the Double-Click Speed slider to control how rapidly you have to click the trackpad button or the trackpad itself to register a double-click.
4.	If you want to be able to "click" the trackpad button by tapping on the trackpad, check the Clicking check box.
5.	Use the Dragging and Drag Lock check boxes to control how you can drag items with the trackpad. If you turn on the Clicking option and then check the Dragging check box, you can drag an item by touching your finger to the trackpad and dragging your finger across it. If you check the Drag Lock check box, the item continues to be locked to the cursor until you release it by tapping the trackpad again.
6.	To disable the trackpad while you are typing, check the "Ignore accidental trackpad input" check box. This option prevents unwanted interference from the unintentional taps on the trackpad while you are typing or just moving your hand across the pad. When you stop typing, the trackpad becomes active again.
7.	If you want the trackpad to be disabled when you connect an external mouse to your mobile Mac, check the "Ignore trackpad when mouse is present" check box.
