							KEYBOARD

The PC keyboard differs from a standard typewriter keyboard in that it has
several extra keys. In total it has 102 keys including a number of special keys
required to control special functions. If you have a look at the keyboard of a
Macintosh or Amiga computer you will see considerable differences from the
PC keyboard.
The letter area begins with the keys Q – W – E - R – T – Y, and so this type of
keyboard is also called a QWERTY keyboard


The Input keys
The main input area corresponds to the typewriter keyboard. You input your
text and simple number combinations using the alphanumeric part of the
keyboard.
   Upper-case or capital letters can be produced by holding down the Shift
    key and selecting the corresponding letter.
   Symbols marked as the second character on keys can be selected by
    holding down the Shift key and pressing the relevant key.
   If you have to type longish sections in upper case, for example headings,
    you can use the Caps Lock key. A green light on the right-hand part of
    the keyboard shows that the Caps Lock key is on. To return to normal
    mode, press the Caps Lock again.


The Enter key
The Return or Enter key on the computer corresponds to the ‘carriage return’
on a typewriter. It is located on the right-hand side of the input keys and is
conspicuous as it is the largest key.
Generally you execute a command and send it to the operating system using
the Enter key. If, for example, you tell your computer that you want to erase a
file, you can use the Enter key or the mouse to confirm the command.
In Word processing this key ends a paragraph in your document.


The numeric keypad
If you want to enter large columns of numbers you can use the numeric
keypad.
Besides entering numbers, the marked keys can also be used for navigating
the cursor around the screen. By pressing the Num Lock key you can
alternate between entering numbers and navigating with the arrows.

Position keys
The six position keys, which are to the left of the numeric keypad, can be
used to quickly position the cursor (= the input marker). The function of the
position keys is program-dependent.
In MS Word:
   The Home key takes you back to the beginning of the line.
   The End key takes you to the end of the current line.
   The Page Up and Page Down keys move your cursor one screen page up
    or down.
   Strictly speaking, the Insert and Delete keys do not belong to the position
    keys even though they are grouped with them in a keypad. In most word-
    processing programs the Insert key switches between Overwrite mode
    and Insert mode.

The four arrow keys, which are directly below the position keys, are used to
move the cursor. The move the cursor one character to the left/right and on
line up/down.


The Function keys
Above the keys used for inputting data you will find twelve keys numbered F1
to F12. These are function keys and are divided into three blocks of four.
Depending on the program used the perform specific tasks. (E.g. F1 activates
the Help function)


The Escape key
At the top left is the Esc key, which aborts the current operation or request
before it is carried out.


Control keys
On the bottom row of the keyboard you will find the Ctrl (Control key), Alt and
Alt Gr key. The two Ctrl keys have the same function. There are only two for
convenience. The Alt key performs a similar task to the Ctrl keys. Both keys
only trigger a function in combination with an alphanumeric key. You can
carry out many standard functions quicker by using key combinations.


Special keys
   Print Screen:    you can use this key to print out the current screen
   Scroll lock:     it can fix the screen in such a way that the arrow keys no
                     longer move the cursor
   Pause:           it does not have any effect on the status of Windows
                     Programs
