you know, some answers seems like illogic for me ..... because in the ground it have no sense !
then with deep observing ...... EUREKA !!! .....I found it ..... we are not using the same keyboard mapping,
I think you are using an QWERTY keyboard, and I'm using an AZERTY one!
with QWERTY keyboard it's right and logic.
with AZERTY one, your answers seems like illogic at all, and not efficient for tactical use mode,
Actually, we Hungarians has also a bit different keyboard layout QWERTZ, thus the Z/Y has common use.
