The Keyboard
The number of keys on your keyboard depends on which country/region's
keyboard layout your computer is configured with. Keyboards for numerous
languages are available.
There are five types of keys: typewriter keys, function keys, soft keys,
Windows special keys and keypad overlay.

Typewriter Keys

The typewriter keys, produce the uppercase and lowercase letters,
numbers, punctuation marks, and special symbols that appear on the
screen.
There are some differences, however, between using a typewriter and
using a computer keyboard:
■
Letters and numbers produced in computer text vary in width. Spaces,
which are created by a "space character," may also vary depending on
line justification and other factors.
■
The lowercase l (el) and the number 1 (one) are not interchangeable on
computers as they are on a typewriter.
■
The uppercase O (oh) and the 0 (zero) are not interchangeable.
■
The CAPS LOCK function key locks only the alphabetic characters in
uppercase while the shift lock on a typewriter places all keys in the
shifted position.
■
The SHIFT keys, the TAB key, and the BACK SPACE key perform the
same function as their typewriter counterparts but also have special
computer functions.
Function Keys: F1 ... F12
The function keys, not to be confused with FN, are the 12 keys at the top of
your keyboard. These keys are dark gray, but function differently from the
other dark gray keys.
