29.3.1.1 Understanding how browse
macros vary by file position
Default definitions of browse macros <$_prev> and <$_next>, and the
meanings of the macro variables these macros employ, vary according to:
- whether the macros produce text
links or buttons (see §29.3.2
Choosing buttons versus text links for a browse sequence)
- the sequential position of the
HTML file in which the macros are invoked; one of:
- a split file that is neither
the first nor the last in the root map
- the first file produced from
the root map
- the last file produced from
the root map.
You can change any of the definitions by changing
the macro code assigned to appropriate navigation keywords; see §29.3.4
Modifying macros <$_prev>, <$_next>, and <$_top>.
