How to restore mouse wheel map zoom?

Hello,

I accidentally assigned a different function to the mouse wheel in the game settings, now I can't figure how to reassign it to zoom for the minimap. "Zoom"-Function in settings is only for zooming your view.

Is the mouse cursor over the map itself when you use the mouse wheel? When it's like that, it shouldn't matter what you have mouse wheel bound to, it should still zoom the map properly. ... I think.
