Arrow keys
The arrow keys are controls for moving up, down, right, and left. You can use these keys
instead of the mouse to move the cursor for navigation on a Web page, in a document, or
in a game.
Numeric keys
Press the Num Lock key to lock and unlock the numeric key functions:
When the Num Lock light on the keyboard is on, the numeric keys work in the same
way as the number keys and arithmetic functions found on a basic calculator.
When the Num Lock light on the keyboard is off, the numeric keys are directional keys
used to move the cursor or play games.
