== Actions ==

Actions are tools that work on a page or the whole wiki, but unlike macros they do not add ''to'' the page content when viewing a page, rather they 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). All subpages could be deleted too.|| This action is not granted if you are not logged in. ||
