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. Icons are used at the bottom of the page to provide redundancy and another representational scheme for diverse users. The Path buttons provide an alternate means of traversing vertically in the hierarchy. As one progresses down the hierarchy, a link label for the page just departed is added to list. Path buttons also allow you to jump more than one level by merely clicking the page link label and to maintain an orientation relative to the site hierarchy.
