Up and down the display list

In the Flash IDE debugger for AS3 I would like to traverse the display list and see the properties of all the objects on the stage. If I place an object on the stage with addChild I can then see it’s reference to the stage in the debugger (this.stage) and stage can be expanded to see various properties. There is also a this.parent and a this.root and this.stage itself has the similar properties.

Using these, how can find “this” and other objects on the stage?

Also, where can I find such technical details?

Many thanks.
