Usage

{{{1}}}
The first unnamed parameter will be interpreted as the name of the subpage to link to. Without a second parameter, this assumes you are linking from the parent page.
prev, lprev, uprev
On subpages themselves, pass in any one of these as a second unnamed parameter in order to link to a different subpage on the parent page. uprev capitalises the first letter of the first argument for the section name, while lprev does the opposite.
s
Pass s= followed by the name of a section if you want to link to a section within the page.
text
Pass in text= to change the text displayed in the subpage link. If this parameter is not specified, the text displayed will default to the section name and then to the first unnamed parameter.
