Python could certainly tie the mouse wheel or a joystick-type thing to a parameter, but I'm not at all sure it would be more convenient than the usual way. Problem is that there's no concept of "Currently Selected Parameter". With lights, cameras, figures, and body parts, Poser has a specific way to select one, and the selection holds. There's no internal way to do that with parameters. So the Python would either have to use its own listbox of parameters, or it would have to detect when you've changed the real dial. Either way would (I think) be less convenient than the usual, because you'd end up using both the regular mouse and the dedicated device. With a joystick, I can imagine a really quick way of operating: the stick's Y slides across the list of parameters, and the X adjusts the selected parm. This could also work with a dedicated separate mouse, I suppose.....
