You can specify where the trail of links should appear on each HTML page: before the heading (that is, the first paragraph in the file), after the heading, or at other locations you specify via [Inserts].
When you specify TrailPosition=Macro, automatic placement relative to the heading is eliminated, and the trail appears wherever you have included <$_trail> in another macro or assigned <$_trail> to a specific location.
For example, to show a trail of links at the top of each HTML file and also at the bottom of each split file after the first, you would assign the <$_trail> macro to a location keyword in the [Inserts] section (see §17.5 ):
When Mif2Go inserts trails specified by a <$_trail> macro assigned in the [Inserts] section, if the first paragraph in the file does not have [HtmlStyles] property Trail, the trail is not displayed. Otherwise, wherever you assign the <$_trail> macro, Mif2Go inserts a trail according to the settings you specify in the [Trails] section.
