You are correct exactly.
But It is difficult to detect the layer if the visibility of serveral layers are ON.
There are 4 layers, TOP, Layer2, Layer3 and Bottom. and the visibility for Layer2 and Layer3 are ON.
and then I selected Pin on Layer3.
In this case, I just want to know a pad in Layer3, but it is difficult now.
Do you know other way to get the layer?
