Chapter 111 TouchPad Basics The following items show you how to use the TouchPad: • Move your finger across the touchpad (1) to move the cursor. • Press the left (2) and right (4) buttons located beneath the touchpad to perform selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad is the same as clicking the left button. • Use Acer Bio-Protection fingerprint reader (3) supporting Acer FingerNav 4-way control function (only for certain models) or the 4-way scroll (3) button (only for certain models) to scroll up or down and move left or right a page. This fingerprint reader or button mimics your cursor pressing on the right scroll bar of Windows applications. NOTE: When using the TouchPad, keep it - and your fingers - dry and clean. The TouchPad is sensitive to finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not increase the TouchPad’s responsiveness.

12Chapter 1 Using the Keyboard Your notebook features a full-size keyboard that functions the same as a desktop computer keyboard. Many of the keys have been assigned alternate functions, including shortcut keys for Windows, function keys for specific system operations, and the Num Lock keys for the numeric keypad. Key Types The keyboard has several different types of keys. Some keys perform specific actions when pressed alone and other actions when pressed in combination with another key. IconKey TypeDescription Function keys Press these keys labeled F1 to F12 to perform actions in programs. For example, pressing F1 may open help. Each program uses different function keys for different purposes. See the program documentation to find out more about the function key actions. System keys Press these colored keys in combination with the Fn key to perform specific actions. See “System Hotkeys” on page 14. Navigation keys Press these keys to move the cursor to the beginning of a line, to the end of a line, up the page, down the page, to the beginning of a document, or to the end of a document. Fn key Press the Fn key in combination with a colored system key to perform a specific action. Windows key Press this key to open the Windows Start menu. This key can also be used in combination with other keys to open utilities. See “Windows Keys” on page 13. Application key Press this key for quick access to shortcut menus and help assistants in Windows. Arrow keys Press these keys to move the cursor up, down, right, or left.
Chapter 113 Windows Keys The keyboard has two keys that perform Windows-specific functions. KeyDescription Windows key Pressed alone, this key has the same effect as clicking on the Windows Start button; it launches the Start menu. It can also be used with other keys to provide a variety of functions: : Open or close the Start menu + : Display the desktop + : Open Windows Explore + : Search for a file or folder + : Cycle through Sidebar gadgets + : Lock your computer (if you are connected to a network domain), or switch users (if youre not connected to a network domain) + : Minimizes all windows + : Open the Run dialog box + : Cycle through programs on the taskbar + : Open Ease of Access Center + : Open Windows Mobility Center + : Display the System Properties dialog box + : Restore minimized windows to the desktop + : Cycle through programs on the taskbar by using Windows Flip 3-D + : Bring all gadgets to the front and select Windows Sidebar + + : Search for computers (if you are on a network) + + : Use the arrow keys to cycle through programs on the taskbar by using Windows Flip 3-D Note: Depending on your edition of Windows 7, some shortcuts may not function as described.
14Chapter 1 System Hotkeys The computer employs hotkeys or key combinations to access most of the computer’s controls like screen brightness, Bluetooth and WiFi. To activate hot keys, press and hold the key before pressing the other key in the hotkey combination.
