This is the site's MAIN WINDOW. Most of the material on this web site will be displayed in this main window. The gray strip on the left is the QUICK NAVIGATION FRAME. It is a collection of shortcuts to often-used features, such as HELP. The shortcuts are context sensitive, meaning that they "know" which page is displayed on the MAIN WINDOW, and they provide services (such as HELP) pertinent to that page.
