Edit Keys
The edit keys are Insert, Home, Page Up, Delete, End, and Page Down. Use these
keys to insert and delete text and to quickly move the cursor on your screen. They
function differently with some software programs.
Arrow Keys
The arrow keys are controls for up, down, right, and left. You can use these keys
instead of the mouse to move the cursor for navigation in 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.
