Pokemon White Exp Action Replay cheats...

I've looked around a bit, not much though... Thing is that I have the exp multiplier codes and the 100% catch rate for the US white version, but I don't know what button activates it. When I play Diamond, I use the R button, but I just don't know what button it is in this version. Any help please?

Also, what is the button to activate Any pokemon can learn any TM/HM ?

I dont get why is it that people ask about the exp cheat and they get ignored :/ I've seen a few times that people ask and either they brush em off or just ignore them. I hope it's just the time, but I've asked this question twice and no answer from anybody...
