on my trackpad, it appears to do that by default

ok, would it in your case be possible to change the number by drawing the mouse up-down? :) (without changing your trackpad settings)

I was just wondering the exact thing, so i threw something together. Seems to emulate it pretty well. This is left-right keys, not the mouse, but it probably wouldn't be too hard to change it up.

Thank you for the patch, I'm afraid it is not that easy to convert the patch. At least not for me. I'll try some more.

Maybe you could just use a horizontal slider connected to a number box?

Btw, I updated my patch so it works the way i originally intended. That is, so if you hold down left and right at the same time it doesn't start spasming.

This seems to work..
