Detailed deep script reference manual

Hi everybody, is there any detailed (deep) scripting reference of the qt scripting language, not just the basic one?

e.g.: I want to control the opacity and set hold-keyframes on it.
So far I managed to set the opacity but no idea how to access hold-keyframe switch on opacity:
node.setTextAttr( node_name, “OPACITY”, frame.current(), opacity);

I just by luck hit the “OPACITY” variable, but that is probably the highest level of oracle I have reached in this case :wink:
