Clicking on these buttons takes you to different places in the Web site organization or structure. We grouped the last three together and called them local navigation buttons. These three allow you to maneuver within the Web site structure based on your current position. A defined hierarchy or organization is very important to this design. The remaining four functions take you to a specific page in the organization.
Hierarchical organization is shown using indentation, much like a textbook.
Hypertext links allow the user to go to the desired page directly from this table of contents. Taken together, these four buttons provide a powerful and complementary navigational scheme that appeals to different users. This appeal is extended to the form of the buttons at the top and bottom of each Web page. Text is used to represent the functions at the top of the page. This provides functionality without interfering with the Web site graphics.
