| As illustrated here by the Tru64 UNIX Documentation Overview, this book is designed as a framed document. It has a Table of Contents, a text panel, and a button panel. In the button panel are buttons to go to the book's index (if there is one) and to open this help window. |  |
| Here, the user scrolls to the bottom of the Table of Contents, goes to a table in Chapter 6, then uses the button panel to go to the Index and from there to some information in Chapter 4 about the man command. | |
