There will also be words within the tutorial that will take you to other places. These are called links. Sometimes, you will click on a link and a second window will open. When that happens, it doesn't meant that the tutorial is gone. You can get back to it by using the desktop taskbar, which is the same bar on which your Windows start button is located. If you open a second window, your desktop taskbar will have multiple buttons. See the picture below:

You can "toggle," or move back and forth between the two open windows by clicking on the buttons in your taskbar with your left mouse button.

If you can't remember how to do any of these tasks, you can always click on "Using" in the bottom menu of each page. If you're ready to continue with the tutorial, use your left mouse button to click once on next.
