Is there any way to disable action queue outside of macro'ing everything?

[Geobryn]

....have I just been playing since PC-Beta without one of the key features or is this just a console thing? O.o I always have to press the key I want and when I want it but no DPS loss since very few attacks can be done at the same time anyway. Seriously not ever come across this but intigued to find out how useful it is.

the queue they are speaking of is not console specific and works in this way
you start to cast 2.5 sec spell > you hit another spell at 2.0 > when the cast is over at 2.5 you start to cast "queued" action
if you go with macros it goes like this:
you start to cast 2.5 sec spell > you hit another spell at 2.0 > game throws an error that you can not use ability while casting
