Function Keys

Arrow Keys

In most cases, the arrow keys help you move around the screen. Like other keys, however, their exact function is determined by the software you are using. On standard keyboards, the arrow keys are on the numeric keypad, along with the numbers. To use these keys properly, the NUM LOCK key must not be active. If NUM LOCK is active, you will type a number instead of changing your position on the screen when you use an arrow key.

On extended keyboards, arrow keys appear to the lower left of the numeric keypad. You can use these arrow keys anytime, regardless of whether the NUM LOCK key is active.

Function keys send instructions to the software you are using. For example, suppose you are writing a memo and you have trouble moving a paragraph. By pressing a function key, you may be able to get Help information on your screen.

Like other keys, what a function key does depends on the software you are using. For example, some software uses F1 to display Help information, whereas other software uses the F1 key for a different function (or may not assign a function to that key at all).

The function keys are located across the top on extended keyboards or on the left side of standard keyboard.
