The computer’s keyboard layouts are compatible with a 104/105-key 
enhanced keyboard - by pressing some keys in combination, all of the 
104/105-key enhanced keyboard functions can be performed on the 
computer.

The number of keys available on your keyboard will depend on which 
country/region your computer is configured for, with keyboards being 
available for numerous languages.

In use there are six different types of keys, specifically typewriter keys, 
function keys, soft keys, Hot keys, Windows special keys and the keypad 
overlay.

The typewriter keys produce the upper-case and lower-case letters, 
numbers, punctuation marks, and special symbols that appear on the 
screen. However, there are some differences 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), together with the 
uppercase O (oh) and the 0 (zero), are not interchangeable on 
computers as they are on a typewriter.

■

The CAPS LOCK function key locks only the alphabetic characters into 
upper-case while the Shift Lock function 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.
