Not sure if this is an intended feature, but after finding this bug report
#781
i get the feeling this is unintended and still happening today in version
11.0.4-retail

Basically key binds don't change via spec or dominos profile which i feel defeats the purpose of having a spec profile or any other profile for that matter besides for action bar layout (which still requires a bunch of mental gymnastics to get the key binds to make sense)
i love dominos thanks tuller

Having the same problem (Ctrl as modifier).
