1.   In the Contents window, right-click anywhere in the left pane.

2.   Choose New Book from the menu or select the new book command from the Contents toolbar.

A blinking cursor appears and allows you to customize the name of the new contents item.

Notice that if you right-click the dead area, choose new book from the shortcut menu, and no book is selected in the left pane, then Doc-To-Help creates a new book after the last book in the outline.
