Is it possible to adjust Lightroom settings with scroll wheel

I don't think it is easily possible to use your scroll wheel to adjust. The only way I can think of is writing a script that translates your scroll wheel action to a up and down arrow key action. but that would prevent you from using your wheel for other actions.

Possible alternative options are:

• Clicking on the number besides the slider and by holding your (left) mouse button and moving your mouse you can now adjust the slider.
• Click on the number then change the number with your keyboard arrow(up/down) keys. This works best for fine adjustments.
• Click on the slider then change the slider with tour keyboard arrow(up/down) keys. This works best for making somewhat bigger adjustments.
