From me just make a brief comment on (casual) Players: Have the keyboard connected via USB and tried to play with the arrow keys: Press two arrows and press an extra on the Num-block (for example to jump) does not.
I highly recommend this keyboard so for arrow keys player not recommend (WASD control I have not tried). 'm Pretty disappointed, even on my old "Internet Keyboard" of Microsoft, I can press more keys ... Conclusion: 1 Star.
