New to HotKeyNet, Don't quite understand basics (How to set up hotkeys)

So I just today decided I wanted to start multi-boxing (I decided I would start low and only play on 2 accounts).

I'm using one computer for both accounts and I'm wondering, how do I set it up so that when I press a key on one wow, It presses the exact same key on the other wow?

I didn't quite understand the tutorials on their website :$

Any help is appreciated :)

Khatovar has some information on her site:

Thanks, I'll have a look :)
