Apple started adding multitouch capabilities to its laptops in the early 2000s. These laptops featured touchpads that could recognize two or more finger taps at once, allowing for easier manipulation of on-screen programs. The most basic implementation of this was sliding two fingers up and down to simulate a mouse scroll wheel. Many PC manufacturers now use multitouch trackpads on the Windows laptops. It's fairly simple to run through the various options and gestures for your Acer Aspire's touchpad.
Turn on your computer and log in. Use a single finger to move the cursor around the screen. To select an item, press the left mouse button or lift your finger and tap the pad once.

Start your Internet browser and go to a basic page, for example, a search engine. (If you do not have an Internet connection available, open a Word or Wordpad document.) Place your index and middle finger on the touchpad at the same time. Slide your fingers up and down without removing them to scroll up and down on the page.
Place two index fingers or your finger and thumb on the touchpad. Slide your fingers away from each other in a diagonal direction to zoom in on the document or page. Slide them toward each other to zoom out.
Start the photo viewer included with your Acer laptop. Select a picture to display. Place your thumb and forefinger on the touchpad. Turn your fingers in a circle to rotate the picture.
