The first thing I want to show you is how to open a second window.
This way you can have this one teaching you things, and another you can practice on. To
use two windows at once is very useful if you are doing more than on thing at a time, ie; checking your e-mail, and monitoring
an online game, or chat room.
When you have more than one window open...you can go back and forth, by pressing the "Alt" key on your keyboard...hold
it down, and tap the "Tab" key. For each tap you will see a list of all open windows, and the title of the one you are
about to open when you release the keys.
