You can find the CTF Codes here: https://www.jazz2online.com/wiki/CTF_Codes
Also you don't have to know all of the ctf, most of the time players use the health ctf codes like "1,2,3" or for enemy's health "e1, e2, e3" or if they ask for the flag carrier's health ("h"). Or at the beginning of the game some ask "a or d" (attack or defend) and you answer with "a" or "d".
