As you already know, your computer mouse lets you move the cursor (pointer) round the screen and then ‘click’ to start a program or begin writing in a particular place or open a menu to see what choices you have.
All desktop computers come with a mouse, and you can use one on a laptop if you don’t like the touch-pad that’s built into it.
wikiHow Staff has created an awesome step-by-step guide to learn about handling and performing very basic tasks using a mouse. You can find it here. I’m sure that you will definitely enjoy it!
