Directional Numpad Notation
In order to represent directional inputs, you use the numbers from a numpad corresponding to the directions ingame:
7 8 9 4 5 6 1 2 3
Commands are always denoted assuming that you're on the left facing right. Keep in mind that the numpad is mirrored when you face from right to left.
When writing down moves and combos, numpad directions combined with a standardized notation can help make them easier to read and understand. Single commands are separated by a space or a >.
A Your A button
B Your B button
xx Cancel: performing the written input immediately after inputting the previous command.
So an example string might appear as j.A > 5A > 5A xx 3A
