Is there a way to parent an objects position to another objects position in Nuke, so they move parallel to each other? I want to move an object parallel to another object in Nuke. I managed to get the object to move to the same position as the other one. (Copy link paste absolute.) But I wasn't able to figure out how to move it relative to the other object. Copy link and paste relative did not work.
You can simply edit the expression values:


create a new Transform Node by hitting T
drag and drop the translation values by holding CTRL from original transform node to the new one (this should create a green line between that nodes)
right click the translation curve icon of the new transform node to open up the Edit Expressions Window 
in this window you can do some math with the existing y or x values to move the the child node
