1. I don't see anything different as far as your FTL Target Me key goes. I would assume there's conflicting key bindings in WoW, likely with Shift+\ or Ctrl+\

2. The only cases of F2 in your configuration are for "BG Macro (Shift+F2)" which would not affect the normal operation of F2. Unless it's unbound/replaced in WoW I don't see why F2 wouldn't have the usual effect

Dunno, neither of these look to be a problem with your ISBoxer config
