Detailed Description

Actions are things which can be done to pages (edit, delete, rollback, etc).

They are distinct from Special Pages because an action must apply to exactly one page.

To add an action in an extension, create a subclass of Action, and add the key to $wgActions.

Actions generally fall into two groups: the show-a-form-then-do-something-with-the-input format (protect, delete, move, etc), and the just-do-something format (watch, rollback, patrol, etc). The FormAction and FormlessAction classes represent these two groups.

Stability: stable: to extend
