Can't remap "V scroll" to "Ctrl + V scroll" (up scroll works, down scroll doesn't)

I'm trying to create a mapping so that I can zoom in/out with mouse. I do this by observing that most browsers and other applications use "Ctrl + scrolling" to zoom in/out.

This is what I configured in the same layer:

Input	Output
V Scroll	Left Control
V Scroll	V Scroll

Then I switch to this layer, Scrolling Up works as expected just like Ctrl + Scrolling Up, but Scrolling Down doesn't work.

Just create another V Scroll->Left Control mapping, but set the scaling parameter to "-1".

It works this way so that you can map scroll up and down to different keys. In your case you just want them mapped to the same thing.

Awesome, it works! Do you have documentation anywhere? This looks like very hard to find out :)

Yeah, I think this behavior was only ever discussed in this issue: #5 and I never updated the documentation.
