[WoW] Keybinds

I apologize if this has been brought up before, but I've been struggling with this for a while and I'm sure you guys have solved this: What are people using for extra keybinds? I have taken to using a lot of windows key combinations in Authotkey (#t, #y, #u, etc) and then assigning them to G15 macro keys or my Xkeys. Similarly I am also struggling with sending modified characters to a WoW window (such as Shift-i which always seems to come out as just 'i').


BTW, a quick blurb about myself since this is my first topic post here: I've been playing WoW since release pretty much nonstop and am a raider. A month or so ago I discovered the Dual Boxing stuff by Xzin and have found a new excitement for the game. I moved my main (70 Druid) to a new account and have been experimenting a lot with dual-boxing my alt (70 Hunter) on PVE content. As an engineer I find it interesting to write scripts to control my characters and as such I have written multiple functions for this purpose.
