This tool displays an editable and fully-functional version of the finished index of your project. This enables you to polish and tidy your index very easily. For example you can quickly correct multiple index entries that are similar, and you can test your index links to make sure that they point to the right places. You can also use the integrated editing tools to assign existing and new keywords to multiple topics in a single operation.
The Index Tool can be used most effectively in combination with the index keyword entry functions for individual topics in the Topic Options tab on the left the main editor window.
