This tutorial uses frames, and therefore should be viewed with a current version of Netscape or Internet Explorer.

On the pages in this tutorial which have frames, the left side of your browser window will contain the tutorial text, with instructions regarding actions to take or links to follow in the righthand frame. You may need to scroll down in the instruction frame to follow along with events in the right.

If desired, the width of the frames can be adjusted by placing your mouse cursor over the frame border and dragging it to the right or left, making it either larger or smaller. The larger your monitor, the easier it will be to use the frames.
