This template manually adds one or more HTML anchors (i.e., link targets) to a page. This allows incoming links to target locations on the page other than section headings.
This allows links of the form
[[#target]] to be used on the same page and links of the form
[[Page title#target]] to be used on a different page (assuming "Page title" is the title of the page this template is used on).
The second example usage shows how multiple anchors can be provided within a single template call. It also illustrates how capitalization differences are significant in HTML anchor names; for this reason, if you suspect that incoming links will try to use targets with different capitalization (or punctuation, whitespace, etc.), then all allowed forms must be explicitly listed in the template call.
Up to 10 targets can be specified in a single template call. If more are needed, a second template call can immediately follow the first.
See w:Template:Anchor for more information, including limitations on valid target names.
