Help! Control Config (MAME, Nesticle, Gens, ZSNES)

[chinabox]

Okay, I'm slowly getting the hang of all this.  However, I'm still having some trouble figuring out how to streamline the controls across several emulators.  It seems like the most logical thing to do is to map the controls of my "secondary" (non-MAME) emulators to the MAME defaults.  However, I'm having some trouble:

a) finding a list of the MAME defaults and
b) changing some of the commands in my other emulators.  For example, in Nesticle (Win), I can't get it to quit back to AdvanceMAME with "ESC".  Do I have to but out a hex editor here?  And if I do, how do I go about doing that?

Here's the software I'm using:

Frontend: AdvanceMENU (Win)
Arcade: mame32v70b1 (Win)
NES: Nesticle (Win)
SNES: ZSNES (Win)
Genesis: Gens (Win)

You'll see a "Windows" motif here, which I am basically doing for usability sake.  And yes, I understand the irony here.  

Thanks in advance for the help!

I'm in the same boat as you, trying to get multiple emulators to work as easily as possible.  It seems from research there are a lot of "custom" emus out there just for this purpose, with use for a front end.  I know Gens has one.  I also saw a thread that detailed how to use a hex editor to make Escape quit Zsnes outright.  I'm sure you'll get better responses than mine, but it is possible.
