20.4.7 Considering an example of browse navigation

Suppose your project involves a FrameMaker document named TechGuide.book that consists of three files: Intro.fm, Examples.fm, and Summary.fm; and suppose you want Prev and Next links at the top of each HTML file generated from TechGuide.book.

In the [Inserts] section of the configuration file you would specify where on each page of HTML output the links should appear (see §20.4.6 Specifying where to invoke a browse macro). For Examples, at the top of each HTML page:

[Inserts]

Top = <$_prev><br /><br /><$_next>

Suppose Mif2Go splits the files in TechGuide.book as follows (see §18.2 Splitting files):

Intro.fm: Intro.htm aa100002.htm aa100003.htm

Examples.fm: Examples.htm bb200002.htm bb200003.htm bb200004.htm

Summary.fm: Summary.htm cc300002.htm

Figure 20-1 shows the positions of these files with respect to the differences in default definitions of <$_prev> and <$_next> (see Table 20-3).

Table 20-8 Values of variables in navigation links for TechGuide.book

HTML file	<$_prev>		<$_next>
	<$$_prevfile>	<$$_prevtitle>	<$$_nextfile>	<$$_nexttitle>
Intro.htm	None (no link)	At Start	aa100002.htm	Intro section 2 title
aa100002.htm	Intro.htm	Introduction	aa100003.htm	Intro section 3 title
aa100003.htm	aa100002.htm	Intro section 2 title	Examples.htm	Brilliant examples and exposition
Examples.htm	Intro.htm	Introduction	bb200002.htm	Examples section 2 title
bb200002.htm	Examples.htm	Brilliant examples and exposition	bb200003.htm	Examples section 3 title
bb200003.htm	bb200002.htm	Examples section 2 title	bb200004.htm	Examples section 4 title
bb200004.htm	bb200003.htm	Examples section 3 title	Summary.htm	Conclusion
Summary.htm	Examples.htm	Brilliant examples and exposition	cc300002.htm	Summary section 2 title
cc300002.htm	Summary.htm	Conclusion	None (no link)	At End

Table 20-8 shows the values that <$_prev> and <$_next> macros would use in each HTML file; in particular:

• For the very first and very last files, the default definitions of <$_prev> and <$_next> do not include links, but only predefined text for titles.

• For all other files, the title is that used in the HTML <title> element, and usually comes from a paragraph or a FrameMaker marker, as determined by settings described in §18.4.2 Specifying page titles for split or extract files.
