I used to do this in the past but forgot. Want to zoom in with mousewheel up and zoom out with mouse wheel down. But also change fov and mouse sensibility.

@raspatan : You would need to write a config binding script using variables. Each "notch" on the mouse wheel will shift you to the next variable - either forward or back within the script. The display settings will update with each change.

There is a basic example located here - forum.fpsclassico.com/viewtopic.php - which might be enough to get you started in writing your own.

If you need more of a hand, let me know and I will have a go at making one too :)
