Turn the touch pointer on or off
If touch input is available on your computer, you can use the touch pointer to accomplish tasks that are difficult to perform with just your finger, such as targeting small objects on the screen. You can turn on the touch pointer when you need it and turn it off when you don't. For example, you can turn on the touch pointer to tap the Close button on a window and turn it off to browse through e-mail messages.
