How do I send command+scroll?

Hi Everyone,

In Keyboard Maestro 9.2 (or higher), how can I send Command+Scroll ? I am trying to zoom in with an application but without using Command+Equals and Command+Minus, since unlike the former approach, the latter approach doesn't zoom in and out based on cursor position. I'd like to zoom in and out based on cursor position, thus Command+Scroll.

Thanks!
