I've noticed that in some html help files (chm), the author
was able to associate text with a folder (book). That is, when a
user clicks on a book (not on a topic), text appears in the viewer
pane--as it does with a topic. I can't seem to make this happen.
What's the magic?
Try right-clicking the book and looking at the properties
dialog. There you should find a check box labeled "Book with link".
Click to place a check mark there and you should then be able to
associate a topic that will display in the topic pane when the book
is clicked by the user.
