5.5.3 Activating hypertext links in a converted index
When you convert a FrameMaker index, only the page numbers in an entry become hypertext links, because each index entry can have multiple links to different parts of your document.
To activate the index links, you must apply a character format to the index-entry page numbers, in FrameMaker. Without the character format, multiple page references for an index entry might cause a crash.
To apply a character format to index page numbers:
1. In the FrameMaker IX file, define a new character format; for example, IXpgnum. The character format can be set to “As Is”.
2. On the IX Reference page of the IX file, find the line with paragraph format IndexIX, which contains the <$pagenum> element, and apply character format IXpgnum to the entire line.
3. Save the IX file, and generate the book. In the Body pages of the regenerated IX file you will see that the page numbers are still links but the index-entry text is not, just as before; so locked FrameMaker documents and PDF files are unaffected.
For HTML output, you can replace each page number with a clickable image; see §13.8.1.3 Replacing page numbers with symbols or images.
