A common, simple type of navigational template in a hierarchy of pages is one with the names, with links, of a parent page and child pages. It is placed on all the pages it lists. Thus a page that is not at the top or bottom of the hierarchy has two templates, one with its parent and siblings, and one with its children.
Variations also occur, such as pages having two parents, etc.
Self links usually do not give any complication: they are neatly displayed in bold and not as links. However, templates should have the correct page names and not rely on redirecting, since this non-linked format does not apply when the self link is created by redirection. There are also some other situations, such as for a link to a page section, when this non-linked format does not apply. See Help:Self link for more information.
A navigational template may also just allow going forward and backward in a linear sequence, e.g. en:Template:Pope. For the predecessor of the first and the successor of the last a message like "none" can be used. This is not applicable in the case of a cycle, such as the days of the week.
