Right and left and a button will make you move while attacking.
Combos: You can make your own but RN here is some programmed in the game. Press A and S in the middle of attacking.
Z and X in the middle of attacking. X and S in the middle of attacking.
X and any other button works too. Z and right or left and X in the middle of attacking(Animation will look different)
Also Try A+A+S Combine keys like that to make even cooler combos
