When I first started out playing, for the first month or so, I thought clicking was the only option. The way I found out about Z and X was through a friend who laughed at me when he saw me playing. When you first start out, the only real ways to figure out are to have somebody tell you, look it up, or make a guess that there are more than 2 trigger keys through a replay. I also feel that it should go over some of the basic terminology, like streams and jumps. Thanks!
