							Chapter 111
Three productivity keys give users one-touch access to protection and manageability features for a more 
secure, smarter and easier way to work.
Lock key - runs the Windows® lock function to lock the notebook when you step out. If the laptop is 
equipped with Acer BioProtect, you only need to swipe your finger to log into Windows® again.
Presentation key - minimizes open application windows and prepares the display for impressive 
presentations.
Sync key - instantly synchronizes your computer system to an external storage device, for convenient 
and secure backup.
Touchpad Basics
The following teaches you how to use the touchpad:
Move your finger across the touchpad (2) to move the cursor. 
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.
Use the 4-way scroll (3) button to scroll up or down and move left or right a page. This button mimics 
your cursor pressing on the right scroll bar of Windows applications. Internet browser (user-programmable)

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 numeric keypad, separate cursor, lock, Windows, function 
and 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.
