Doc-To-Help also allows you to convert an existing subtopic into a main topic. The topic remains in the same position in the Help system’s outline, but is converted from a topic to a book.

1.   In the Contents window, select a subtopic that you would like to be converted into a book.

2.   Click the Convert Topic command in the toolbar.

Alternatively, you can right-click the topic you want to convert into a book and select Convert Topic to Book from the shortcut menu.
