A Sub-Header word is a word that will be written indented inside the Index as a child for a Header word. The program allows 4 levels of words in the Index(Header, Sub-Header, Sub-Sub-Header, Sub-Sub-Sub-Header), each level will be written under its parent indented. Here is how you can create it:
1. Generate your index normally till you reach Step3 in the program.
2. Double click a word (ex: Transportation) to edit it. The Edit word dialog will appear to edit that word.
3.Set the Word type selection box value to Header word. The Sub-Headers button beside the Word type selection box will become enabled.
4.Click on the Sub-Headers button to define all the sub-header words for the Transportation word. The Sub-Headers dialog will appear.
5.Enable all the sub-header words that you want to specify for the Transportation word.
6.Click Apply to apply the changes.
7.Repeat the above steps for all your Header / Sub-Header words, then when you write the final index to a PDF file, you will find the specified Sub-Header words indented under their Header words as you have wanted.
