Any way to rebind the free camera control button?
 

Is there any way to bind this function to a different key. Incase I didn't make it clear what I'm talking about, its when you hold in the middle mouse button and it lets you position the camera to your liking. But there is no key binding option for it in the options menu.

As my middle mouse button is broke on my mouse, I'd like to change it to a different button. But without it appearing in the options I have no way of doing this. Any ideas?

If you press numpad number buttons you can change rotation, zoom and tilt etc.

Yea I tried using them but they are incrediably awkard and you can't get the exact angle you want :)

Mouse wheel is best especially in direct control when you quickly need to rotate the camera to where you are aiming. Any modders know where the userconfig is kept, maybe i can edit the controls there.
