The attack button has a few different functions, depending on the way the directional pad is pressed before hitting this button.
Just the button(no motion)= a flurry of punches and kicks, this
will deflect fireballs(starting move for all the grab and
attack moves, also regular grab and attack on Playstation)
Forward, Forward+Attack= grab and attack(combo starter)(on the Playstation, this must be done during normal flurry of hits attack)
Forward+Attack(during any grab and attack)= knock opponent across the screen
Back+Attack(during any grab and attack)= knock the opponent the opposite way across the screen
Up+Attack= hit that knocks opponent into the air
Down+Attack= hit that knocks opponent downward onto the ground
Back, Forward+Attack= knocks opponent left or right across screen
Half circle from right to left+Attack(grab and attack)(during
normal flurry of hits attack)= grab and attack pushing your
opponent upwards with hits(the initial flurry of hits has
to make contact) It does not matter which side of your
opponent you are on.
Half circle from left to right+Attack(grab and attack)(during

Just incase anyone else wanted to know them there you go. And thanks Hibiki for telling me where to find them.
