4 Using the keyboard and pointing devices Your computer allows easy on-screen navigation with a keyboard and pointing device. Select models also have action keys or hot key shortcuts that enable you to do common tasks. The TouchPad enables you to perform on-screen functions similar to those by an external mouse. To explore the pointing device features and to select preferred settings: 1. Click the System menu icon at the far right of the top panel, and then click System Settings. 2. Click Mouse and Touchpad. Use an external USB mouse (purchased separately) by connecting it to one of the USB ports on the computer. NOTE: Depending on the country or region, your keyboard may have different keys and keyboard functions than those discussed in this section. Using the action keys An action key performs an assigned function. The icons on the f1 through f4, and f6 through f12 keys illustrate the assigned function for that key. The f5 key performs the function listed in the table below. To use an action key function, press the key. The action key feature is enabled at the factory. You can disable this feature in Setup Utility (BIOS). See Using Setup Utility (BIOS) and System Diagnostics on page 40 for instructions on opening Setup Utility (BIOS), and then follow the instructions at the bottom of the screen. To activate the assigned function after disabling the action key feature, you must press the fn key in combination with the appropriate action key. CAUTION: Use extreme care when making changes in Setup Utility. Errors can prevent the computer from operating properly.
