When jogging, holding down the "w" key and then clicking on the right mouse button (as if to raise weapon) while still holding the "w" key, player enters a non-stop jogging mode. Pushing other keys will not stop the jogging. You can change direction, but not change to a walk. You cannot crouch or change position or go to third-person view. The only way we've been able to stop jogging is to change weapons, and this doesn't always work.
