A keyboard is equipped with small
objects called keys. These keys are the real objects that give meaning to the
keyboard. The keyboard is made useful when you press a key and something
happens.
The keyboard is made of three main categories of keys. Each category is used for a different purpose. The end-goal is to help your computer experience be as effective as
possible. Many companies that manufacture computers equip their
keyboards with additional keys. For example, the following HP
keyboard has buttons to increase the volume of the computer and even to get
on the internet:

The following description relates only to
the QWERTY keyboard used in US English. If you are using a different
keyboard layout or language, consult the documentation that came
with it or the MS Windows Help files. |
|
Key Categories: Character Keys |
|
The first category is made of keys used to display readable characters on the screen. To display
a character or to get the equivalent character of a key,
you have to press its corresponding key. The keys in this category include:
| Letters |
a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t,
v, w, x, y, z |
| Numbers |
0, 1, 2, 3, 4, 5, 6, 7, 8, 9 |

Unlike the mouse, the keyboard shows its presence on
the screen only when you are typing (in a text-based document). In that
case, the object that shows the presence of the keyboard is called a caret. We will come back to it when we perform word processing. The caret allows you to know what section of the document
would receive a letter that you type. If you are typing in a text
document, it is important for you to know
at all times where the caret is.

|
- To open an application, on the Taskbar, click Start
- Position the mouse on Programs or All
Programs
- Position the mouse on Accessories
- Move the mouse down and click Notepad
- To experiment with some of these keys, press each of the following
keys I N D O W S 9 8

Key Categories: Action Keys |
|
A second category of keys are those not used to type anything, instead they cause an action. Some of these special keys are:
| Key Name |
|

 |
|
|
| Up Arrow |
 |
Left Arrow |
 |
Right Arrow |
 |
Down Arrow |
 |
| Space Bar |
 |
The letters you typed in the previous section are referred to as lower case or
lowercase. To type their equivalent uppercase, first press and hold a Shift key .
While the Shift key is down, press the key corresponding to the letter you want.
If you wanted to type only one uppercase letter, after typing, you can release
Shift. Otherwise, you can keep Shift down and type the desired uppercase
letters. At the end, release the Shift key.
If you plan to type a lot of
uppercase characters, you can press the Caps Lock key. This causes the keyboard
to display a light, usually on the upper-right section of the keyboard of a
desktop or on the Caps Lock key itself. After typing the uppercase characters,
press the Caps Lock key again to turn the light off.
Besides being used to type uppercase letters, the Shift key also allows you to
access the upper base of the keys that display two of them. Such symbols are:

From now on, and throughout this web site,
unless specified otherwise
- The words "Click", "Right-Click",
"Double-Click", and "Drag" always refer to the
mouse. Remember that the word "Click" always refers to the
left mouse button (I keep repeating this because I have had my share
with students, very frustrating for me: Click is always the left mouse
button, not the middle, not the right, always the left, always!!!)
- The word "Press" always refer to the keyboard

Application-Dependant Keys |
|
The third category of keys is mainly subject to programmers' choice. These are called function
keys. They are F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, and F12. Although the F1 key is usually used to get help while working in Microsoft Windows, the use of the other keys
varies from
one application to another. Eventually, the application you use will give you instructions on what to do and how to use the function keys.

Practical Learning: Using Application-Defined Keys
|
|
- While Notepad is still displaying, press F1
- Notice that the Help file opens
In the Action Keys section, we saw that some keys
could be
combined to produce uppercase letters or to access the upper symbols of
some keys. Keys are also combined for many other reasons. When this site
a book or any other document wants you to combine keys, the request will usually specify how to
use or press those keys; this sometimes differs from one book
or document to
another.
In some situations, you have to press keys simultaneously, which means that you
may be expected to press two or more keys at the same time, or almost at
the same time. In some other situations, you may have to press and release
one key, followed by another.
For our lessons on this site, here are the
conventions we will use:
| if you are asked to |
Do this |
| Press T |
- Press the T key once and release the key (you press and release
immediately; you don't hold the key)
|
| Type t |
- Press the T key once and release the key
|
| Press Ctrl + T |
- Press and hold Ctrl
- While you are still holding Ctrl, press the T key once and release
it
- Then release Ctrl
|
| press Ctrl + Alt + Delete |
- Press and hold Ctrl
- While you are still holding Ctrl, press and hold Alt
- While you are still
holding both Ctrl and Alt, press Delete once and release it
- Then release the other keys
|
| press Alt, V |
- Press the Alt key once and release it
- Then press the V key once and release it
|

A shortcut is a quick action you ask a program to perform when you press one particular key or a combination of
keys. Some shortcuts are universal or almost, that is, the computer responds regardless of what application is running.
Some other shortcuts depend on what you have on your screen.
When to use a shortcut, you will be directed so. If
the shortcut is made of one key, you will be specified the key. If the
shortcut is a combination, you will be given the combination as we
reviewed them earlier. Whenever you open a menu and decide not to use it anymore, press Esc.
Some shortcuts are already known to the computer (as part of the operating
system). Most other shortcuts are set by the programmer of the particular application you are using. Yet some applications allow you to create your own
shortcuts. Some shortcuts are readily obvious and can be seen from the main menu of the application. Some other shortcuts are either part of Microsoft Windows (and can be applied in your program) or are not easily displayed, you might have to search the Help documentation of the program you are using.
