Imagine that your foot on the active engine side is attached to your thrust lever/throttle. If you increase thrust you push in more rudder at the same time and visa versa. The other important thing is keep the control wheel level. If it's not level you either have too much or not enough rudder in. Step on the downside. In other words, if your controls are turned to the right to keep you going straight, step on the right to straighten the controls. Always be thinking to adjust your feet to keep the controls level. Good luck. We've all been there.
