The procedure in the 737 operating manual for the takeoff roll is to keep the airplane on centerline with rudder pedal steering and rudder.
The tiller should NEVER be used on takeoff and this point should be made more explicit in the operating manual. It seems like an obvious point, but American Airlines had to add this to its operating manual following their A300 crash:
The rudder in a large transport airplane is typically used for trim, engine failure, and crosswind takeoff and landing. A rudder input is never the preferred initial response for events such as a wake vortex encounter, windshear encounter....
Instructions in the operating manual would be slightly less direct than a placard next to the tiller.
Not to be Used for Directional Control During Takeoff or Landing
