All right, stupid question time. When people talk about certain inputs, usually they use a combination of numbers and letters. I'm pretty sure I know what the letters mean (L-Light, M-Medium, H-Heavy, S-Special). What are the numbers (e.g., 2H, or 214M)? Are they positions on a stick?
The numbers represent directions - they mirror the number pad on a key board.

The assumption is always that your character is on the left side so 8 is up, 6 is forward, 2 is down, and 4 is back. A quarter circle forward motion looks like 236 (start at down and roll to forward).
