Anyone use HotkeyNet? Everyone here seems to be talking about ISBoxer/Pwnboxer.
HotkeyNet is completely free and personally, I've found it to be much more straightforward than trying to get one of these old/cracked GUI options working.

That should have everything you need to get started with some basic things. Just use one of the example scripts and modify it to meet your specific needs.
I use it in conjunction with Jamba addon and that's all I need.
If anyone has some interesting or useful scripts for it, I'd be curious to see them.
I'll share some of mine later once I'm on my other machine I use to MB.
