WebCT remembers how you navigated the path for the duration of your stay within that path. Refresh acts the same way the Refresh command works on a web browser. It will re-open the page you are on, refreshing any updated information. Contents takes you back to the table of contents page. The navigation bar can also hold links to other sections of the course.
Instructors can link to audio or video files, graphics, etc.
There can also be links to other tools, such as the glossary, my notes, or mail. These are explained a little more indepth later in this guide.
