I idn't actually get what you meant there. I've never heard of key input being used with conditional branches.
As far as i know, you're meant to set a combination of buttons and a result (for example, pressing enter makes you start jump, move forward, end jump. Or pressing up, down, up, down makes you gain 99 levels.....)
How it actually works tough, as i said on the other thread, i'm not sure how you actually et it all up, but i'm fairly certain that that's how it rolls....
