Funny nobody has mentioned a useful kick my instructor taught me: he calls it the "ecology kick", and its purpose it to protect to avoid damaging or disturbing the environment below you - be it sand, silt, or coral - while still providing a good low profile trim and enough power to move efficiently. It goes like this:
You kind of cross your legs so that both fins are above each other. The bottom leg does not move and is relatively straight. With the top leg you do a flutter kick. When the top fin comes down, it pushes the water onto the bottom fin, which in turn directs it toward the back, effectively creating a jet propulsion effect.
It's not that difficult to master, but can be quite tiring. I find I frequently have to swap legs.
