Strictly above statment would include Limit Break.
But ideally I think you should be able to access LB without interrupt your movement.
By the way, if a players doesn't care some info that needs to check by opening a window,
then that's completely unnecessary to put the shortcut to this window on his xhotbar.
So if someone don't need to check gears and tomes simultaneously, ofcoz he will not use crosshotbar slot for fast checking.
