== Actions ==

Actions are tools that work on a page or the whole wiki, but unlike macros do not add ''to'' the page content when viewing a page, but work ''on'' that page content. They either produce some output based on page contents (navigational actions like searching) or implement functions that are not related to viewing a page (like deleting or renaming a page).

There is a set of system-defined actions, which includes page editing; you can extend the set of known actions by your own ones. See HelpForDevelopers for more on that.

The following actions are added to the list of user-defined extension actions at the bottom of each page (or in the "More actions" menu). This happens to any mixed-case extension, for other actions (all lower-case) see the list further down this page. Some of these action might not be available for your wiki site.

||<tablewidth="100%">'''Action'''||'''Description'''||'''Remark'''||
||<-3>`AttachFile`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> attach files to a page, see /AttachFile for more details. || This action is not granted if you are not logged in. ||
||<-3>`DeletePage`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> Delete a page, after you confirmed it; deletion means a final backup copy is created and only then the page is deleted, i.e. you can ''revive'' the page later on (as long as the backups are not physically deleted). || This action is not granted if you are not logged in. ||
||<-3>`RenamePage`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> Rename a page, after you confirmed it. || ||
||<-3>`LikePages`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> list pages whose title starts or ends with the same MeatBall:WikiWord as the current page title.|| ||
||<-3>`LocalSiteMap`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> show nearby links of the current page, i.e. list all referred-to pages, and in turn their references, to a certain limited depth. || ||
||<-3>`SpellCheck`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;">call the spell checker for the current page; see HelpOnSpellCheck for more. || ||
||<-3>`SubscribeUser`     ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> Administrators can use it to subscribe other users to pages || ||

The following is a list of ''internal'' actions that are used to implement the various icons and links at the top and bottom of pages, or supplement certain macros.

||<tablewidth="100%">'''Action'''||'''Description'''||'''Remark'''||
||<-3>`titleindex`    ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> Implements the listing of all page names as text (append `?action=titleindex` to your wiki address) or XML (`?action=titleindex&mimetype=text/xml`); the main use of this action is to enable MeatBall:MetaWiki.|| ||

||<-3>`inlinesearch`    ||
||<5%>[[BR]]||<^ 75% style="margin: 10px;"> this implements the inline search for the form fields at the bottom of each page (note that this uses POST requests, so you won't normally see this action in URLs).|| ||
