Well, I don't have a 'physical' main.

It's a bit complicated but the following should be understandable if you are familiar with the leaderless concept. I just took a twist to it.

Basicly, when I press Left Arrow or Right Arrow on a toon, it sends two other keys to the other chars. With the same keymapping on the others. So when I swap leaders, it always turns the three then current alts. I basicly got a bit of an advanced FTL set up that includes all my movement and position keys. So I can get away with using just my NT52E for just about all my needs with the ability to instantly change leaders by just moving to another screen. Very fun to upset people in arena during fights too. But also allows me for instant reaction to swap leaders in the case my leader does die. Which shouldn't happen, but when it does, it doesn't neccesarily mean a loss this way. All the while keeping my alt rotation keys in working order.

1PC by the way, or a laptop. I've used both with other programs but I found one pc is better (and easier to manage) for PvP and such set ups. :P

I'm currently brainstorming on setting up an FTL system the way I want it across two pc's however, but have been running into some problems. It's a project at the moment. ;(
