When you have an index you are happy with — and are almost certain the publication will not change — you can often still improve your index with local formatting. For example, if you only have one entry each under the headings “W,” “X,” “Y,” and “Z,” you might combine them into a single heading for “W–Z.” Or you might want to use the Find/Change dialog box (Edit menu) to apply type styles to certain words. Remember that the changes will not be reflected in future versions of the index if you decide to delete or change entries at this stage.
