Thanks for the reply.

I tried those as root, but got an error:
# xinput --list
No protcol specified
Unable to connect to X server

So I tried again as a normal user and got results:
bash-4.3$ xinput --list

It looks like I'd want to do something with "Button Wheel Up" (142), 
"Button Wheel Down" (143) but it's not clear what I should do. Any ideas?
