I use my left shift key on computer.
The only weird thing is that if you press the shift 5 times while there you turn off the speaker or lower it all the way to 0.
You will still hear that noise, and the speaker is off. How the Hel# did that sound come up and I hear it even the speaker off?
I don't really get it.
Try it for yourself
1. lower your speaker all the way or turn off your speaker
2. press the left shift key 5 or 7 times
3. the box come up and the sound come up
