You set your rules/conditions via the program window shown above. Therefore you are still able to use your mouse wheel to, lets say, scroll a webpage: With volumouse you set certain conditions when you want the mouse wheel to change volume and the volume will only be controlled when these conditions are met. Volumouse is a simple and lightweight program that allows you to control the volume on your computer by just scrolling your mouse wheel. However, would it not be convenient if you did not have to use those buttons at all rather you could just scroll up or down using your mouse wheel to change the volume. Some of us have dedicated buttons on on laptops/speakers that allow us to control the volume of out computer some of us don’t.
