Acer Aspire E1-430P - Manual (Page 32)

12 - Using the keyboard
Scroll Lock
When Scroll Lock (<Fn> + <F12>) is on, text on the screen moves one line
up or down when you press the up or down arrow keys. Scroll Lock does
not work with most applications.
Num Lock
When Num Lock (<Fn> + <F11>) is on, the embedded keypad is switched
to numeric mode. While Num Lock is on, hold <Fn> to temporarily type
letters.
Embedded numeric keypad
The embedded numeric keypad is indicated by
small characters located on the upper right
corner of some keys. When Num Lock is on,
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.
Tip: It is possible to use the cursor-control functions provided by full
keypads. If Num Lock is on, hold <Shift>, if Num Lock is off, hold
<Fn>, and then tap the required key. Cursor-control key symbols are
not printed on the keys.
