What you are refrring to is known as low speed reject. If it happens with live engine at TOGA(Max thrust) it becomes more challenging as the yaw towards the dead engine is very rapid. Use of Nosewheel steering at high speed causes it to skid on wet runway and may be very viscious on dry so it is not recommended till taxi speed is reached. The correct procedure is to bring both thrust levers to idle, that removes the cause of the yaw and use both thrust reversers, the live engine acts as differential brake. If this not sufficient differential braking can be used on the live engine. It is very important to have adjusted the rudder peddles properly so that your foot can apply full differential braking. Runway excursion has happened due to improper adjustment. Inflight use of asymetric thrust can be done but is not a normal occurrence.
