How do you zoom in and out on your laptop?

There are several ways. An easy way when you are using the internet is to hold the 'Ctrl' button and then press '+' until you're happy with the zoom. To go back out, you hold 'Ctrl' and '-' instead until you feel it has returned to its original size.
If you want to point and zoom at something, go to your start menu, and open the all programs option. Go to Accessories, then go to ease of access, and choose the magnifier option.
