Hi there..welcome to the forums!~..
Your best bet...is to ask when u get to what it is u are attempting to do..I find that works best..The possibilities are endless with script..so..who knows if what you need would be posted either way..kind of thing..
However that being said, Chromegloss has made a thread here with help for beginners,intermediate..ect..with scripting..
Here's the link..maybe u may find it useful..

As for Keygaurd..a few of us have used it..perhaps one of us could help..
It's alot easier than what it looks..don't let it intimidate you..
Peace
