(though shalt not hit enter) As $SUBJECT, all passive keygrabs are rejected due to the fake XIAll(Master)Devices devices not having a KeyClassRec. This mustn't matter though, since the grab itself will never establish on the fake device anyway, only on a slave device. And that has a KeyClassRec, it can't send key events otherwise.
