Function keys
The function keys (not to be confused with the Fn key) are the
12 keys at the top of the keyboard.
Sample 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 “Fn-esse®” on
page 152, or “Hot Keys” on page 208.
Windows special keys
Sample Windows special keys
Your computer’s keyboard has two keys that have special
functions in Windows:
❖Start key—Opens the Start menu
❖Application key—Has the same function as the
secondary mouse button
Overlay keys
The keys with gray numbers and symbols on the front of
them form the numeric and cursor overlay. This overlay lets
you enter numeric data or control the cursor as you would
using the 10-key keypad on a desktop computer’s keyboard.
