HOW TO USE A COMPUTER:
Step 1: Have a good look at your keyboard. The most important keys are labelled on the diagram below:
Some keyboards, especially those on laptops, will have a slightly
different layout. For example, yours might not have a number pad or the
delete key may be in a different place. But virtually all keyboards will
have these important keys somewhere.
Step 2: The main keys are the letter keys. When
you type just using these, you get lower-case print. However, if you
hold down a ‘shift key’ (there are two to choose from) at the same time
as you type, you’ll get UPPER-CASE letters.
Try typing your name, including capitals (UPPER-CASE) and spaces.
The ‘space bar’ (which you press briefly to make a space) is the wide
key at the bottom of the keyboard.
Step 3: If you make a mistake in your typing, there’s always a remedy.
To delete a letter, place your cursor (mouse pointer) just after the letter and click. Then press Backspace briefly.
(Always press briefly – otherwise, you’ll get repeated deletions,
spaces, letters or whatever.) Or place your cursor just before the
letter, click and press Delete.

Step 4: Now try typing a sentence:

This is a good sentence to practise because it contains most of the letters of the alphabet.
Step 5: You can move the cursor along this sentence without deleting anything by using the arrow keys:

Try moving the cursor backwards and forwards through your sentence.
Step 6: Now try using the number pad, if you have one.
To use this to type numbers, you have to press the Num Lock key. There may be an indicator light at the top of the keyboard or on the ‘Num Lock’ key itself to show that it’s on.

Step 7: You can also type using the numbers on the main keyboard. You’ll find them on the row of keys above the top line of letters.
Above these numbers are various symbols, which include ‘£’, ‘&’, ‘!’. To use these, hold down the Shift
key while you type. So if you press ’7′ on its own, you get ’7′, but if
you press ’7′ while you hold down the ‘Shift’ key, you get ‘&’.
Try typing:

You’ll find similar extra symbols elsewhere on the keyboard:

They operate in exactly the same way as the ones above the numbers.
Step 8: If you want everything to appear in upper case, press the Caps Lock key and then type:

Again, an indicator light may come on to show that your capitals
are ‘locked’. Don’t forget to press this key again when you’re finished
to turn ‘Caps Lock’ off.

Step 9: The ‘Windows’ key comes in a number of different designs, such as the example to the right.
It does exactly the same thing as the Windows button on the taskbar
on your computer screen. You can choose to open the ‘Start’ menu by
pressing this key or by clicking the button on the taskbar with your
mouse.
Step 10: There are a number of ways that you can move round a web page. Try using the keys below to see where they take you:

Step 10: You’ll be told to use the ‘Control’
(Ctrl) and ‘Alternate’ (Alt) keys for some operations. When you do so,
keep holding down one or the other key or both keys while you press any
other keys.

For example, if you press Ctrl, Alt and Delete all at the same time, a menu will open. To make it disappear, press the ‘Escape’ (Esc) key in the top left-hand corner of the keyboard.

Step 11: Some of the things that you use the mouse
for can be done with keyboard shortcuts. These require you to hold down
one key while pressing another, and often involve using the ‘Ctrl’
and/or ‘Alt’ keys. Some people prefer using them to using the mouse.
