Check out the "how to" section sticky`d at the top for starters. You might want to watch the lesson video as well to pick up a top or two. What you need to start getting the hang of is "torsional steering" using the flex of the board to twist it in the direction you want to go by using your ankles, knees and hips. The rear foot is along for the ride most of the time. In steep terrain or riding muguls, you will push and pull the rear foot more than on a groomer, but the turn is still initiated with the front foot.
For edging, going from heel to toe, use the hips to shift over your edge more and not leaning you entire upper body. This keeps most of your weight centered over the top of the board in all phases of the turn.
