Takata, it may take a hand to trim the rudder, but if you are a pilot, you are taught to fly with your feet. (I understand that some people are taught to stop doing that ... ) The point of the trim (particularly if we are discussing manual trim versus auto trim) is to set a new rudder position so that you don't have to keep making smaller and smaller inputs.
From the diagrams I have, there are rudder pedals on the Airbus 330.
Using your feet to move the rudder is a skill taught from Hour Zero in anyone's flying career ... a skill that appears to atrophy with disuse.
