What is the mod that zooms in the camera?

Just as the title asks what mod is the zooming thing from when u press left ctrl. I'd like to either turn it off or re-map it b/c left ctrl. is my push-to-talk key. Any help would be appreciated.

It's from OptiFine. You should be able to just remap it in the ingame control option.
