+* `pagenames` - If given instead of `pages`, this is interpreted as a
+ space-separated list of links to pages (with the same
+ [[SubPage/LinkingRules]] as in a [[ikiwiki/WikiLink]]), and they are inlined
+ in exactly the order given: the `sort` and `pages` parameters cannot be used
+ in conjunction with this one.
+* `trail` - If set to "yes" and the [[!iki plugins/trail desc=trail]] plugin
+ is enabled, turn the inlined pages into a trail with next/previous links,
+ by passing the same options to [[ikiwiki/directive/trailitems]]. The `skip`
+ and `show` options are ignored by the trail, so the next/previous links
+ traverse through all matching pages.
