_root.movieClip_root.action_root.property
movieClip The instance name of a movie clip.
action An action or method.
property A property of the MovieClip object.
Property; specifies or returns a reference to the root movie Timeline. If a movie has multiple levels, the root movie Timeline is on the level containing the currently executing script. For example, if a script in level 1 evaluates _root, _level1 is returned.
Specifying _root is the same as using the slash notation (/) to specify an absolute path within the current level.
Note: If a document containing _root is loaded into another document, _root refers to the Timeline of the loading document, not to the Timeline containing _root.
The following example stops the Timeline of the level containing the currently executing script:
_root.stop();
The following example sends the Timeline in the current level to Frame 3:
_root.gotoAndStop(3);
