Function keys
The function keys, located above the main keys, are labeled F1 through F12. Most function key operations vary by software program. F1 and F3 are available at all times:
Pressing F1 opens a Help window for the software program being used.
Pressing F3 opens a search window.
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 the screen. The edit keys function differently with some software programs.
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.
