I don't know that there's many people left that still use or remember how to use AutoHotKey. Maybe someone will come around and be able to help, but if not, I'd suggest ISBoxer or HotKeyNet. ISBoxer is subscription based but has a setup wizard and tons of users. HotKeyNet is free and script-based - there is a guide for it in my Sig. There are also tons of guides and how-tos in the first Multiboxing Guide {also in my sig} for ISBoxer, HKN and some other programs.
