events for actor transform


I am writing a plugin and I like to listen on actor transformation in editor and game mode. For example, if an actors transformation is changed by setting values with the keyboard in editor mode, **OnRegister **is called. I searched the documentation for further events without luck.

Which event is raised when the actor is transformed by mouse in editor mode?
Are there in general events like ‘on transform start’ or ‘on transform end’?
And is it possible to listen on an actors transformation in game mode?
