Magic Mouse - Pinch in / Pinch out gesture for zoom in or zoom out


Hello every one,

I kindly ask for your help in setting magic mouse gesture (pinch in) to (zoom in).
As the only option i can choose from predefined actions is (smart zoom) but not (zoom in).

Note: in pinch-in? I get the following explanation but I don't know how to perform it

( Pinch In If you want to use this gesture for zooming you can either use the predefined actions zoom in / zoom out, or use custom keyboard shortcuts (cmd + or cmd -). This gesture may need some advanced configuration in order to work properly. Check out the advanced mouse preferences and go to the last tab (other gestures, zoom etc.))

I appreciate your assistance.


A kind reminder, please


Can anyone please direct me where I can contact the developer directly for my question?


This is currently not possible, you can assign cmd+ and cmd -, but Apple doesn't provide a way to produce the native zoom events.


Thanks for your reply.
