The N and Z in the Street Fighter 4 move list are what buttons on the joystick.

N means back to the center, that is, the joystick back to the original position, and then it is the "P" "K" key, P stands for PUNCH = fist K stands for KICK = foot and the discussion of the "J" that is JUMP, which means jump, so LP | MP | HP and LK | M | HP and what is the key on the handle. K is for KICK and the "J" in the discussion is JUMP, which means jump, so LP|MP|HP and LK|MK|HK mean Light Punch, Medium Punch, Heavy Punch and Light Kick, Medium Kick, Heavy Kick and in general, commands such as "LP+LK" are connected with "+" to refer to the "P" "K" key. In general, commands such as "LP+LK" with a "+" refer to pressing these keys at the same time. Speaking of which, there are some moves in SF4 that are labeled as inputting the arrow key commands and then inputting PP or KK, or even PPP or KKK, etc., which refer to pressing the keys at the same time, i.e., pressing the light punch | the middle punch together, etc., and not just hitting them in quick succession for three times. After you understand the basics of how to do this, here is the terminology that is used in normal communication. Attack Determination The range or distance at which a character is able to attack an opponent when making a move. The character leans back due to the impact of the attack, and is unable to input any commands on the hardened side

COUNTER HIT Hits the opponent first at the moment of the attack, causing the opponent to suffer a hardened or more severe damage

FLOATING When the character is knocked into the air, and can be pursued

BLOWING When the character is knocked into the air, and can't be pursued

THROWING When in close quarters, you can use →/←/N LP. The attack where you type →/←/N LP+LK, and you can't defend against it, which is also commonly referred to as a "slam" or "backpack."

SA is short for SAVING ATTACK, and it's also the core skill of SF4. A move in which the opponent is unable to defend against or dodge subsequent moves because of the first hit

Storage For example, Guile's Sonic Hand Knife ←Storage→+P, which involves holding down ← for a certain amount of time and then typing in →+P

Meets A combination of moves formed by typing in commands in a specific tempo

Special moves are those that require a certain amount of familiarity with the character's performance and moves

Continuous moves/COMBOs are combinations of single directional keys, such as attack keys.
