20.4.6 Specifying where to invoke a browse macro
To specify where in an HTML output file to invoke one or more browse macros, in the [Inserts] section assign the macro(s) to one or both of the following keywords:
Top = <$_prev><br /><br /><$_next><br /><br />
See §18.5 Inserting HTML code in split and extract files for additional [Inserts] keywords you can use to specify other file locations, and for keyword prefixes you can use to restrict macro assignment by output file type.
