Karabiner seems like an extremely versatile piece of software, but I can't seem to find a way to invert the mouse axis with it. For example: When I move the mouse downwards I want the cursor to go upwards, and when I move the mouse to the right, I want the cursor to go left.(*)
Right now I'm using USB Overdrive for this purpose, but I need Karabiner for other stuff, and it would be nice if I could get away with just one program.
(*) This sounds so strange that I feel I owe you an explanation: I have a trackball mouse which, due to it's form factor forces me to turn it 180 degrees on my desk. By inverting the axis in software, it still moves naturally.
