Download the latest VIA software from caniusevia.com to remap keys. If the software does not recognize your keyboard, contact support for instructions.

3. The Layers

The keyboard has four layers of key settings:

• Layer 0 and Layer 1 are for the Mac system.
• Layer 2 and Layer 3 are for the Windows system.

If the system toggle is set to Mac, Layer 0 is activated. If set to Windows, Layer 2 is activated. When using in Windows mode, make changes to Layer 2, not Layer 0, to avoid common mistakes.
