Marvel vs Capcom Macros

I'm new to emulators so bear with me. :msn_shy:

I'm trying to figure out macros and I've learned that I need to place them into the .ini folder and then configure the keys to the macros. No problems there. However, I'm stuck on exactly what needs to go into that file. If I wanted to create a macro for a certain character's super move, what letters am I typing? Is there a code that represents each maneuver or something? Also, I'm amazed at how much trouble I'm having finding a simple list of the characters' combos codes. Can anyone help with that?

Thanks, folks.
