The document describes the various keys found on a computer keyboard. It discusses the typical typewriter keys like character keys, shift key, caps lock key, tab key, enter key, space bar, control and alt keys, and backspace key. It also covers the function keys, numeric keypad, arrow keys, and other computer-specific keys like print screen, scroll lock, insert, delete, home, end, page up, page down, pause, and escape keys. The keyboard allows users to type letters, numbers, and symbols similarly to a typewriter but also enables additional computer functions through specialized keys.

Character Keys
The keys are marked with letters,
numbers, and symbols.
Shift Key
Like the typewriter , pressing any letter
and holding down the shift key
simultaneously will give you capital
letters. You can also use the shift key
to type the symbol indicated at the
upper portion of the key.

The caps lock key is just above the left
shift key. It acts as an on-off switch.
Pressing it once will capitalize all the
letters you type.

keyboard. You will use these keys in
combination with the other keys.

The backspace key deletes the
character to the left of the cursor.

labeled F1 through F12 called
function keys. As you will learn,

to simplify your entry of numbers when
you enter data into a spreadsheet or
some other applications that requires
the entry of many numbers.
