>>===About actions===
Actions are small (or not so small) pieces of code that generate automatic content within a page. An action may provide simple content, or it may provide an interactive "service" with a form for user input.

===Post-formatter actions===
{{since display="inline" version="1.3.6"}} There are two types of actions: Those that act on the wiki page prior to the markup being processed ("traditional" actions, designated by ""{{...}}""), and the new **post-formatter actions** (designated by ""{{{...}}}""). The main difference between the two is that the new post-formatter action can access the contents of the wiki page it's invoked in after the markup has been processed into HTML. For instance, the new ""{{{...}}}"" post-formatter action will generate a table of contents for all headings on a wiki page, and uses the id generated for each heading by the Wikka formatter. Since this can't happen prior to the page being rendered by the formatter, ""{{{...}}}"" must be implemented as a post-formatter action.

Some actions are considered "core" and are essential to the functioning of Wikka as a WikiEngine. Others are better classified as "plugins", providing extra, less essential functionality. Of course, WikkaWiki comes bundled with all "core" actions and a nice collection of "plugins". Many Wikka users also make [[http://wikkawiki.org/CodeContributions | additional plugins]] available through the main site.

===Using actions===
To include an action in a page, simply edit the page and add the name of the action between double braces, e.g. ##""{{myaction}}""##. Action names are case-insensitive.

Many actions can be customized by providing extra parameters; a parameter must always have its value enclosed in double quotes, e.g. ##""{{myaction par1="foo"}}""##. Unknown parameters are simply ignored; in some cases one or more parameters may be required. Multiple parameters are separated by spaces: ##""{{myaction par1="foo" par2="bar"}}""##.

----
==Content example:==
Use ##""{{wikkaversion}}""## to display the version of Wikka running this wiki:
~{{wikkaversion}}
----
==Service example:==
Use ##""{{googleform}}""## to display a Google search form. You may add an optional ##q## parameter to specify a default search query, as in ##""{{googleform q="Wikka"}}""##:
~{{googleform q="Wikka"}}
