5The 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.
Please make sure the system toggle on
the top left corner has been switched
to the same system as your computer's
operating system.
