I just WASTED 8 hours trying to get this to work. Nothing I read or searched for gave me any clues as to what I was doing wrong. It turns out something is limiting my ability to pass Ctrl+F7 to the WoW window. I dont know if windows reserves this key combination or what, but every hotstring that used ctrl+FX(any function key) would not work. Alt and shift were fine. I finally got it to work as described in the OP by using [.
I believe WoW has the Ctrl + FX keys bound to the special action bar as default (warrior stances, druid forms, paladin auras etc). Did you make sure to unbind them from there?

I myself use Ctrl + F1-F5 as my keyclone PiP keys, and I'm pretty sure WoW recognises them too.
