Erzeugt eine automatische Navigation innerhalb eine Kategorie oder für eine Semantic Mediawiki Suchabfrage. Vorgabe-Layout ist platzsparend als Pfeile, jedoch kann mit dem Parameter <code>show=…</code> Linktext (<code>show=text</code>), eine lange Navigation (<code>show=navigation long</code>) sowie Bilder (<code>show=images</code>) statt Pfeilen ausgegeben werden. Falls der aktuelle Seitenname nicht mit in der Kategorie geführt wird, kann ein abweichender „Vergleichs“-Seitenname mit <code>compare with</code> vergeben werden.

(1) Die Vorgabe ergibt zwei Pfeile:<br/> [[File:Go-previous.svg|24px|link=Weymar 1976]]{{!}}[[File:Go-next.svg|24px|link=Weymar 1988b]]<!--
    -->{{Hidden
       | style       = border:1px dotted black;padding:0.25em;
       | toggle      = left
       | contentstyle= border-top:1px dotted;padding:0.25em;
       | 1= {{Logo | Tip | 15px}} Beispiele:  <code><nowiki>{{BrowseByAskQueryPreviousNext | [[Kategorie:Literatur]]}}</nowiki></code>
       | 2=
<source lang="html4strict">
{{BrowseByAskQueryPreviousNext | [[Kategorie:Literatur]]}}
<!-- 1 oder query == #ask-Abfrage-->
{{BrowseByAskQueryPreviousNext | 1 = [[Kategorie:Literatur]]}}
{{BrowseByAskQueryPreviousNext | query = [[Kategorie:Literatur]]}}
<!-- compare with == falls abweichend von Seitenname (=Vorgabe)  -->
{{BrowseByAskQueryPreviousNext | query = [[Kategorie:Literatur]] | compare with = Weymar 1988b}}
</source><!--
    -->}}<!-- Hidden::end -->


(2)  Mit dem Parameter&nbsp;<code>show=text</code> ergibt sich:<br />
«&nbsp;[[Weymar 1976]]&nbsp;{{!}}&nbsp;[[Weymar 1988b]]&nbsp;»
<div style="border:1px dotted black;padding:0.25em;"><code><nowiki>{{BrowseByAskQueryPreviousNext | [[Kategorie:Literatur]] | show = text}}</nowiki></code></div>


(3) Mit <code>show=navigation long</code> wird Text mit Pfeilen nach der [[Vorlage: Navigation]] erzeugt:
{{BrowseByAskQueryPreviousNext
  | query = [[Kategorie:Bombus]] [[Kategorie:Artbeschreibungen]]
  | show = navigation long
  | link up = Schlüssel zur Bestimmung von Hummeln
  | link up text = Hummel-Schlüssel
  | compare with = Bombus campestris
}}
{{Hidden
       | style       = border:1px dotted black;padding:0.25em;
       | toggle      = left
       | contentstyle= border-top:1px dotted;padding:0.25em;
       | 1= {{Logo | Tip | 15px}} Beispiel: <code>show = navigation long</code>
       | 2=

  | show  = navigation long
  | link up      = Schlüssel zur Bestimmung von Hummeln
  | link up text = Hummel-Schlüssel
}}
</source><!--
    -->}}


(4) Mit&nbsp;<code>show=images</code> werden stattdessen Bilder ausgegeben (10 = Voreinstellung). <code>show=50.images</code> erzeugt hingegen 50 Bilder.

(5) Mit&nbsp;<code>show=books-left-right-floating</code> werden Bücher links und rechts gezeigt. Alle Inhalte, die danach folgen, fließen um die Piktogramme herum (dieses Verhalten kann man mit <code>&lt;div style="clear:both;">&lt;/div></code> aufheben):<br/><!--

== Technische Dokumentation ==

Die Vorlage setzt das [[Attribut: {{#var: propertyPageName}}]], das nötig ist um Vorgänger und Nachfolger innerhalb einer Suchabfrage zu bestimmen.

Variablen: pagesafter (Zahl), pagesbefore (Zahl), pageafter (Seite), pagebefore (Seite)

Zu tun: Bug in {{Abk.|SMW}} wenn Seiten abweichende Sortierung → Falsche #ask Ergebnisse
