Hi, I am sure from my first PPL lesson, I was told to use the rudder pedals to taxi, and maintain the nose wheel on the yellow lines all the way around the airfield, even on the 90 degree corners, of which there were many.
For my first T/O at 4 hours, the instructor said to wait for 60 knots, so I watched the ASI... 45, 50, 55.... Then he said 'Watch where you are going', as we were about to mow down the runway edge lights! Still not too sure if this was an instructor induced rudder control, but I certainly remember that lesson.
If the OP has no idea of what the rudder pedals, and brakes do, he should be asking more questions.
