This one is from my experience of Cinema 4D where you simply place the mouse cursor inside the spinner entry field and roll the mouse up/down to change the values. In Max the problem/s I have are (1) The teeny-weeny arrows are near impossible to select individually for changing values up or down and (2) I find I need to drag the mouse across the room to change the values by any significant amount. No doubt there's a setting for that (somewhere) but incorporating the simple "place cursor in spinner and roll mouse wheel" seems so much more intuitive and ergonomic as well.
