You just pressed them on your keyboard.
press LP+RK+LK.
press LP+RP he will do laser or add up forward+RP+LP or down forward+RP+LP or press LK+RK he will fly then press RP+LP he will do laser.
Hwoarang has 2 special moves. The first one, just like Baek Doo San's special move is arrow down back + RK + LK. The second one is flamingo stance (arrow forward + LK) then press LP + RK. The second one inflicts more damage than the first one and its execution time is longer.
There are 4 ways to make Devil Jin Fly in Tekken 6. Fist is the laser grab. Press arrow key forward, back, down, forward + LP+RP. Second one is press RK+LK. In this move, he will only fly but will not execute an attack unless you press a command like LK. The third one is side step + RP. This move is like an uppercut but Devil Jin will fly and hit with a laser if you press up arrow + RP upon impact of the uppercut. The last one is forward. down forward + LP. This is like the third one, to make him fly press arrow forward.
throw or grab is done upon pressing LP+LK or RP+RK on all characters. some characters have special grabs or throws specially King and Armor King that they have a lot. Paul and Lilli's special grab can be done by pressing down+forward+RP+LP all at the same time. the Mishimas and Roger Jr and Brian Fury's special grab is forward, forward+RP+LP.
press num lk button
All characters in Tekken have the same grab commands and each character has 2 grabs. One is LP+LK (you can use forward arrow along with the grab to increase range) and RP+RK also you can use the forward arrow key. Some characters have special grabs exclusive for themselves and it is executed in different key commands. For example of special grab, for Lili the command is arrow forward down + RP+LP also the same with Feng Wei.
Practice it. Alternatively, you could make this easier by using L1,R1,L2,R2 to make the combo easier. (ETC. You could use L1 to do LP-LK,RP-RK, etc etc.) I did this with devil jins 10 hit combo (the one with 4 circles and a triangle at the end) and i land it every time! c: Hope this helps. ~Dan
