I want to trigger a function when maya auto keyframe. Is there any callback for Maya autoKeyframe function?

Seve, 

There is a callback when autoKeyFrame is enabled. That can be accessed via a scriptJob with MEL or python. 

The API MMessage class gives you more robust control over callbacks and messages. For example http://help.autodesk.com/view/MAYAUL/2018/ENU/?guid=__cpp_ref_class_m_anim_message_html

Yes I know the scriptjob and MAnimMessage class. But a question is that they only provides events when keys are edited.But you won't knew whether the key is modified, deleted, or added. And you won't know the key is changed/added by setkeyframe or autokeyframe. 

Is there any way for those information?
