That's actually less of a single sequence of moves and more like a rhythm game that looks different from region to region. The standard version goes like this: you clap on your thighs, then clap your hands together, then left thigh, right thigh, hands again - and you do the whole thing in rhythm while everyone's shouting "Schnitzelbank." Some versions have extra moves like snapping or pointing, but the basic pattern is actually pretty simple once you've done it a couple times. The main thing is just keeping the rhythm and not falling out of sync - it gets faster and faster.
