It that checks the context you are pasting in and the type of node you are trying to paste in some cases.
For example, it will paste copied nodes in geo level as sop imports when pasting in lops and it wil paste cop networks as an image node when working in a materialXSubnet.
I bind it to ctrl + shift + v
