The Acer Aspire D255 has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock, function and special keys.
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 |
When Num Lock is on, the embedded keypad is in numeric mode. The keys |
<Fn> + <F11> |
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. |
|
<Fn> + <F11> only for certain models. |
|
|
Scroll Lock <Fn> + |
When Scroll Lock is on, the screen moves one line up or down when you press |
<F12> |
the up or down arrow keys respectively. Scroll Lock does not work with some |
|
applications. |
|
|
