Simple script, but I only tested it for a bit, so I hope it works well. You can adjust the increments by changing the numbers (+2 and -2) in the script.
Code: Select all
~RButton::
hotkey, WheelUp, Volup, on
hotkey, WheelDown, Voldwn, on
keywait, RButton
hotkey, WheelUp, off
hotkey, WheelDown, off
return
Volup:
soundset, +2
return
Voldwn:
soundset, -2
return
