Move object in Physics Asset Editor

I haven't edited a physics asset in ages. I remember you can press a button to grab the asset and move it around whilst your simulating physics for testing.

How do I grab and move around the physics asset whilst simulating physics? What do I press? Can't find the information for the life of me it's such a simple thing that isn't intuitive.

Update:

Hold Shift -> Rightclick

What a fk around
