[insert move here] cancel= use a move then dash before the second part of the move. Kitana's df+1+R2 can be cancelled with uf and uf punch and lead to a combo.

Instant Air [insert move here]=Using a move so quickly once you jump that its hurtbox is both on the ground and in the air. E.g. U DF+1 with Kitana is an IAF (Instant Air Fan)
Some moves get special properties when instant aired e.g. Scorpion falls to the lowest height and teleports, he will skip the punch (he will land instead of punching) and appear next to them. That's an instant air teleport.
