Ctrl, Fn, and Alt keys
 
(Sample Illustration) Ctrl, Fn, and Alt keys 
The 
Ctrl, Fn, and Alt keys do different things depending on the 
program you are using. For more information, see your program 
documentation.
Function keys 
The function keys (not to be confused with the Fn key) are the 12 
keys at the top of the keyboard. 
 
(Sample Illustration) Function keys
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 TouchPad. For 
more information, see “Hot Keys” on page 210.
