   *VIA only works when the keyboard is connected by wire to the computer.
6. The Layers
   

   There are four layers of key settings on the keyboard. The layer 0 and layer 1 are for the Mac system. The layer 2 and layer 3 are for the Windows system.	If your system toggle is switched to Mac, then the layer 0 will be activated.	If your system toggle is switched to Windows, then the layer 2 will be activated. Remember that if you are using it in Windows mode, please make changes to the layer 2 instead of the top layer (the layer 0). This is a common mistake people are making.
