Hidden jsfl methods

Hi folks - i’ve been scouring the net trying to find a resource which details the undocumented flash api features - the only one i know of from flash guru seems to be offline! I’m developing a flash extension and as part of it i need to write code to add guides to the stage via jsfl - something which isnt in the published macromedia docs, but must exist. Any links / info would be most useful!!

thanks all.
