I was looking at some videos of best shots in fifa07.... and i noticed that almost every ball was curled...so.. i'm asking you guys which button on Keyboard is for curling the ball

Thank's for your answers

D/y-d + R + ->/<-

how ?? D/y-d + R + ->/<- All i get are the arrow keys and Shot button (D).... what the other keys stand for ? y-d+R
