Across the top of a keyboard are a row

is composed of the letter F and a number,
ranging from F1 to F12. Each of the
Function Keys performs a specific
operation based upon what software is
being used.

section to the right that contains the
Numeric Keypad. This consists of the
numbers 1 through 9, an asterisk, a slash,
a dash, a plus sign, an enter key and a
period. There is also is a "Num Lock" key,
which is used to turn on and off the
Numeric Keypad.
