Macro function
Up to 15 successive button commands can be assigned to any of
the four shoulder buttons using the macro function. Pre-programmed
button combinations are a huge advantage particularly during complex
fight simulations. In addition, the combinations can be programmed in
incorporating a time interval, of which there are two to choose from. The
macro function can be assigned to buttons L1, L2, R1 and R2.
