5.4 Builtin Index Macros ======================== RefTeX by default recognizes the ‘\index’ and ‘\glossary’ macros which are defined in the LaTeX core. It has also builtin support for the re-implementations of ‘\index’ in the ‘multind’ and ‘index’ packages. However, since the different definitions of the ‘\index’ macro are incompatible, you will have to explicitly specify the index style used. Creating Index Entries, for information on how to do that.
