HOW TO MAKE USE OF A COMPUTER KEYBOARD

Follow these step-by-step instructions to help you get to know what your keyboard can do:
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.

STEP 6: 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.
