Narrative:

After landing (captain's landing) we took a high speed and I started after landing checklist after clearing the runway. I looked up and we were headed off the taxiway. The captain had the power levers in full reverse however were unable to stop and went off into the grass. The captain noted we had no steering and was unable to steer with differential braking. As soon as I noticed our direction of travel I confirmed the right speed lever full aft, which engages the nose wheel steering. Steering worked the previous 3 legs and nothing was apparent to be broke during preflight.
