Shift + Scroll remap

[Danny Bochkov]

HI!

I was wondering if someone could help me out with this. 

I'm used to shift+scroll being the universal horizontal scroll command

FL studio has a predefined function for shift+scroll and it's dumb lol. 

People have figured out a workaround on Windows with AHK: 

+WheelUp:: Send, {WheelLeft} return +WheelDown:: Send, {WheelRight} return

I'm trying to achieve the same thing with Karabiner on mac, could someone point me in the right direction?

Thanks in advance!
