Trolli,

I’ve searched for them and have come up empty. The built-in actions appear not to be the same as added actions. Most 3rd party actions are not available either, as they’re saved in a run fomat that can’t be decoded. Some of the 3rd party actions contain scripts which can be opened and edited, but not many.
