13.8.1.4 Making index entries into links
If your index has only one destination per entry, and you are certain this will always be the case, you can make the text of the entries act as links, and hide the page numbers. Use the procedure explained in §13.8.1.3 Replacing page numbers with symbols or images, with the following exceptions:
• Specify something that is not visible in place of the symbol or <img> tag; for example:
• Make each index-entry paragraph into a hotspot:
This method uses ParaLink, a setting meant for TOCs, to specify that the entire paragraph should be the hotspot for any link it contains, regardless of any character format applied. The “?” in Level?IX is a wildcard that makes the setting apply to all level numbers.
