The template {{anchor}} inserts one or more HTML anchors in a page. Those locations can then be linked to using [[#link|...]] syntax.
Examples
1. {{anchor|foo}}
could be linked to with [[#foo|...]] from within the same article,
or it could be linked to with [[articlename#foo|...]] from other
articles and from redirects.
2. Anchors can be more suitable for inter-article linking than section titles are. For example,
== {{anchor|foo}} Section title ==
Here, links via [[articlename#foo]] would remain valid even if the section were renamed.
3. The template can be used to create up to ten anchors with a single call. For example,
{{anchor|foo|bar|baz}}
will create three anchors that can then be linked to with [[#foo]], [[#bar]] and [[#baz]].
Specifying more than 10 anchors will cause an error message to be displayed.
