MediaWiki:Viewprevnext/qqq
This is part of the navigation message on the top and bottom of Special pages which are lists of things, e.g. the User's contributions page (in date order) or the list of all categories (in alphabetical order). ($1) and ($2) are either Pager-older-n ("older $1") and Pager-newer-n ("newer $1") (for date order) or Prevn ("previous $1") and Nextn ("next $1") (for alphabetical order).
It is also used by Whatlinkshere pages, where ($1) and ($2) are Whatlinkshere-prev ("previous $1") and Whatlinkshere-next ("next $1"). ($3) is made up in all cases of the various proposed numbers of results per page, e.g. "(20 | 50 | 100 | 250 | 500)". For Special pages, the navigation bar is prefixed by "(Page_first ("first") | Page_last ("last"))" (alphabetical order) or "(Histfirst ("Earliest") | Histlast ("Latest"))" (date order).
Viewprevnext is sometimes preceded by the Showingresults ("Showing below up to $1 results starting with #$2.") or Showingresultsnum ("Showing below $3 results starting with #$2.") message (for Special pages) or by the Linkshere ("The following pages link to $1:") message (for Whatlinkshere pages).
