Keyboard

The different keys
A workstation keyboard displays the following types of keys:
Alphabetic Keys - Represents the letters of the alphabet, the punctuation marks, and
•
text-formatting functions such as Tab, Return, and the Space bar.
Numeric Keys - Represents the numbers from 0 to 9. They are located near the top of
•
the keyboard and in a numeric keypad on the right side of the keyboard.
Navigation Keys - Used to move the insertion cursor (up, down, right, left). These
•
keys are commonly called arrow keys and are represented on the keyboard by the
symbols. This category comprises the keys like Home, Page Up, Page Down, and End
also.
Modifier Keys - used in conjunction with other keys to modify the meaning of these
•
keys. They are Ctrl, Shift, or Alt keys.
Special purpose Keys - they have particular functions and are labelled to specify their
•
function. They are, for example, the Help, Esc, Enter, Delete, BackSpace, and Insert
keys.
Location and insertion cursor
This cursor takes the form of an I-beam pointer. It indicates where the text is going to be
entered. This cursor is frequently met when using Entry boxes (see next paragraphs). The
cursor can be moved horizontally and vertically using the Navigation keys.
