Examples
A simple Index entry for subgroup which will link to its definition.
The first two (placeholder) <idx> entries below provide distinct search points
in the Index for a normal subgroup. Note that because of their arbitrary
placement in the text, they refer only to the subsection and not to a
definition. The third <idx> creates an entry under the category notation for
the symbol \trianglelefteq (sorting it in the notation list as if the label
were normal), and leading the reader to consult the definition for a normal subgroup.
The first <idx> tag creates an entry in the Index for the subcategory field extension under the main catergory normal (with a link to its definition),
while the second adds the suggestion to consult Galois extensions.
Both <idx> tags are necessary. Note that with the placeholder index entry at
the end of the example, there are now two subcategories (subgroup and field extension) under the category normal in the Index.
