It is really important for people to be able to play the ball quickly. For example, if you are playing left defence you can cross the field with one pass but it needs to be quick and accurate and the ball needs to be low.
Steps:
Hold your hands like a normal sweep at the top of the stick
Timing is important, at the moment of the impact and when you hit the ball, make sure your stick is straight
The point of impact with the stick must be in the middle
