(move a control down to "grab" the object and move it down) I use opposite directions on my trackpad and my scrollwheel, take that! Ha! Trackpad I’m grabbing with my fingers so I want the surface to move in the same direction as my fingers. Scrollwheel I feel like is a roller that sits on top of the surface so I have to roll down to make the surface move up. Unfortunately, at least in macos, you need 3rd party software to achieve this
