Touchpad
The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor 
responds as you move your finger across the surface of the touchpad. The central location on the palmrest 
provides optimum comfort and support.
Touchpad Basics
The following teaches you how to use the touchpad:
TMove your finger across the touchpad (2) to move the cursor.
TPress the left (1) 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.
TUse the 4-way scroll (3) button (for selected models) or Acer BioProtect fingerprint reader (3) supporting 
Acer FingerNav 4-way control function (for selected models) to scroll up or down and move left or right a 
page. This button or fingerprint reader mimics your cursor pressing on the right scroll bar of Windows 
applications. 
						

							12Chapter 1
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.
NOTE: By default, vertical and horizontal scrolling is enabled on your touchpad. It can be disabled under 
Mouse settings in Windows Control Panel.

Using the Keyboard
The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and 
twelve function keys, and two special keys.
Lock Keys and Embedded Numeric Keypad
The keyboard has three lock keys which you can toggle on and off.
The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters 
located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols 
are not printed on the keys.
Lock KeyDescription
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock 
 + When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a 
calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you 
need to do a lot of numeric data entry. A better solution would be to connect an external 
keypad.
Scroll Lock 
 + When Scroll Lock is on, the screen moves one line up or down when you press the up or 
down arrow keys respectively. Scroll Lock does not work with some applications.
