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:
T Move your finger across the touchpad (2) to move the cursor.
T Press 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.
T Use 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.

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.
12 Chapter 1
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.
Lock Key Description
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock
<Fn> + <F11>
Scroll Lock
<Fn> + <F12>
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.
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.
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.
