Hotkeys? (VBA/NO$GBA)

These emulators have some annoying hotkeys that sometimes screw me over in games, such as the f-keys loading earlier savestates, or with NO$GBA, Alt+X closing the emulator. Is it possible to modify the hotkeys for either of these emulators? If so, how?Edit: Ah, thanks. I checked VBA again and found the "Customize" function. I wasn't able to find a way to disable the Alt+X closing NO$, (and dang is that annoying, Alt is right next to X, which I prefer to use as my B button >.<) but I guess I can live with that.

For no$gba, press F11, then go to the "controls" tab.
-I forgot how VBA works, but I think you need to go to the "Options?"
