Usage

This template is designed to be passed to a navlist, which describes the organization of a book as documented at Template:Navlist/Doc. Its function is to identify the predecessor of {{PAGENAME}} in the book outline. The result generated prefixes {{BOOKNAME}} to the predecessor page entry as it occurs in the navlist; if no predecessor is found, nothing is generated. Looking backward in the list of pages from the current page, one or two blank entries may be skipped.

Some examples (see note on editing):

Description	Code	Result
module isn't in navlist	{{Template:Navlist/Doc/A\|=Template:Navlist/Map/Prev page}}
module is first in navlist	{{Template:Navlist/Doc/F\|=Template:Navlist/Map/Prev page}}
skip 2	{{Template:Navlist/Doc/D\|=Template:Navlist/Map/Prev page}}
