14 Chapter 1 Launch Keys Located at the top of the keyboard are four buttons. These buttons are called launch keys. They are designated as key 1, key 2, key 3 and key 4. By default, key 1 is used to launch the internet browser and key 2 is used to launch the e-mail application. Keys 3 and 4 starts the Launch Manager application. All four keys can be set by the user. To set the launch keys, run the Acer Launch Manager.
Chapter 115 Touchpad The built-in touchpad is a PS/2-compatible pointing device that senses movement on its surface. This means that the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimum comfort and support. NOTE: When using an external USB or serial mouse, you can press Fn-F7 to disable the touchpad. If you are using an external PS/2 mouse, the touchpad is automatically disabled. Touchpad basics The following items teach you how to use the touchpad: 1. Move your finger across the touchpad to move the cursor. 2. Press the left (1) and right (3) buttons located on the edge of the touchpad to do selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad produces similar results. 3. Use the center (2) buttons (top and bottom) to scroll up or down a page. This button mimics your cursor pressing on the right scroll bar of Windows applications.
16 Chapter 1 NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping harder will not increase the touchpad’s responsiveness.
