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. See Creating Index Entries, for information on how to do that.
