The Keyboard
All T2150CD series computers’ keyboard layouts are compatible with a 101/102-key
enhanced keyboard. By pressing some keys in combination, all the 101/102-key keyboard
functions can be executed on the computer.
The number of keys on your keyboard depends on which country’s keyboard layout your
computer is configured with. Keyboards for numerous languages are available. These optional
international keyboard layouts are illustrated in

There are five types of keyboard keys: light gray keys, function keys, dark gray keys, soft
keys and overlay keys for keypad entry and cursor control.
Light Gray Keys
The light gray keys, like standard typewriter keys, produce the upper- and lower-case 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 (l) and the number (1) are not interchangeable on computers as they
are on a typewriter.
The uppercase O (o) and the zero (0) 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
BkSp
(backspace) key perform the same
function as their typewriter counterparts but also have special computer functions as
described in the following sections.
F1...F12 Function Keys
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.
F1
through
F12
are called function keys because they execute programmed functions when
