Girder Automation Software Setup

Right now I am using WMP 9.0 with the option to put the controls in the toolbar. I want to use Girder to assign the scroll wheel button the ability to skip to the next song. It looks as if this is a possibility using the software but I have yet to figure out how to set it up right. When using this I will have WMP in the taskbar instead of opened full screen in case that makes a difference. Thanks in advance!
