Can I map mouse mouse buttons 3 and 4 to control the system volume? Is it possible to map mouse buttons 3 and 4 to control system volume on a Mac? KeyRemap4Macbook doesn't seem to have the functionality, nor SizzlingKeys. I have them both. Is there some way to manually bind these buttons to control system volume?
What kind of mouse? Is there a proprietary driver for it?  Kensington has a driver for their mice &amp; trackballs that can assign their buttons.  Before I had  an effective Kensington driver, I used USB Overdrive. It works with a lot of multi-button HID devices.
