.)x

.)x [page] [author]

End index entry started with .(x. Print index with .xp.

The arguments are optional. If page is "_" (an underscore), the page number for this index entry is omitted. Otherwise, page is the page number to use instead of the one that is automatically calculated.

The second argument is printed right-justified at the end of the entry; it might be used for the author's name, for example. If author is specified, page must be too: use \n% to get the current page number.
