yes, one action per window and that's all legal
but what I'm not too sure about if it' legal to send random keys when spamming one key
at least Blizz removed /castrandom which "essentially" did the same thing, but was more limited
I think that they aren't even able to monitor this, since we could just spam 3-4-5 with our fingers and that would also create randomness
however I LOVE this ability and will continue to use it until I'm told otherwise not to
