X-Mouse Button Control (XMBC) allows you to set a variety of controls for your mouse. For example, you can set a button copy, paste, undo, volume up/down, forward-backward (in browser), scrolling background windows and many more.
Changes can be application-specific, meaning simply changing applications will automatically swap mouse controls, but they can also be user-managed and based on a hot-key. So your mouse can work as basic volume controls for your music player as well as back and forward buttons for your browser.
A 64-bit version is available (within the folder).
