Need simple training macros for keyboard


For example, right now I need to train crouching combos in SF3 3S (playing on FBA emulator for GGPO), so I need to set up my keyboard to always press “down”. Or, I want to learn counter to Chun’s lightning legs - need macros for rapid pressing “Num 3” (roundhouse kick on my keyboard).

What programs/tricks can I use for these or other similar tasks? I’ve already had no success with Autohotkey and Macrogamer - either I couldn’t set it up or FBA blocked it as cheating.
