Although your computer’s keyboard layout is compatible with a 
standard full-size keyboard, it has fewer keys. 

A standard full-size keyboard has two 

Enter

, 

Ctrl

, and 

Alt

 keys; 

editing keys; cursor positioning keys; and a numeric keypad. 
Pressing the

 Fn

 key simultaneously in combination with one of the 

specially marked keys allows you to emulate a full-size keyboard. 

Your computer’s keyboard has only one 

Enter 

and one 

Ctrl

 key. Most 

of the time, this does not matter. However, some programs assign 
separate functions to the right and left 

Ctrl

 and 

Alt

 keys, or to the 

regular and numeric pad 

Enter

 keys on the full-sized keyboard. 

Using the 

Fn

 key, you can simulate these separate keys, as follows:

❖

Press 

Fn

 and 

Ctrl

 simultaneously to simulate the 

Ctrl

 key on the 

right side of the enhanced keyboard.

❖

Press 

Fn

 and 

Enter

 simultaneously to simulate the 

Enter

 key on 

the numeric pad of the enhanced keyboard.

The 

Ctrl

, 

Fn

, and 

Alt

 keys do different things depending on the 

program you are using. For more information, see your program 
documentation.

The function keys (not to be confused with the 

Fn

 key) are the 12 

keys at the top of the keyboard. 

F1

 through 

F12

 are called function keys because they execute 

programmed functions when pressed. Used in combination with the 

Fn

 key, function keys marked with icons execute specific functions 

on the computer. For example, 

Fn+F9

 turns off the Dual Pointing
