How to find out the driver object in SDK?

[hzhou3]

Hi, in a scene having hundreds of nodes, how to find out the driver object in SDK (set-driven key)? I tried to check in Set Driven Key window but nothing in it. I also tried to check in the Graph Editor but there is no indicating label on the curve. So if I have a scene containing hundreds of nodes and I want to determine what the SDK driver object is, what should I do? Thanks a lot.

PS: I am using Maya 2017 Update 2.

Select node with SDK applied to it in Channel box then RMB click or Click Edit and choose Select Connection then open Node Editor then click Input/Output connections to bring them in work area, marquee  select all node in node editor then press 3 to see what connection else.
