The macro for Kazuya Mishima's combo character in the game Tekken 8 allows the player to perform a certain sequence of actions by pressing only one button. 

For the macro to work correctly in the Keyran program, you will need to configure the following parameters: 
1. Enable the use of the driver. This will allow the macro to work coherently with the game and perform combos without delay.
2. Disable the use of minimum delay. This will allow the macro to perform combos as quickly and efficiently as possible.

Follow the instructions below to set up the controls in the Tekken 8 game:
1 - Assign the Num 4 key to action «1».
2 - Assign the Num 5 key to action «2».
3 - Assign the Num 1 key to action «3».
4 - Assign the Num 2 key to action «4».
Up - Assign the «W» key to move up.
Down - Assign the «S» key to move down.
Left - Assign the «A» key to move to the left.
Right - Assign the «D» key to move to the right.
