Here’s a cute utility to turn your mouse into a volume control
Those clever people at Nirsoft have a nice utility to use your mouse as a volume control for your computer.
Volumouse is a free utility with good configuration options.
The mouse wheel becomes a volume control when you press the Alt key, when the left mouse button is held down or the mouse pointer is hovering over the taskbar — you get to choose.
All you need is a wheel mouse and Windows 98 or above. There are multiple language files available for global support.
Give it a try … its easier and faster than clicking on the volume controls in Windows.
