1. 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. 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.
-
DeletePage: 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).
-
LikePages: list pages whose title starts or ends with the same
![[MeatBall]](/wiki/rightsidebar/img/moin-inter.png)
WikiWord as the current page title.
-
AttachFile: attach files to a page, see /AttachFile for more details.
-
LocalSiteMap: show nearby links of the current page, i.e. list all referred-to pages, and in turn their references, to a certain limited depth.
-
SpellCheck: call the spell checker for the current page; see HelpOnSpellCheck for more.
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.
