Shortcuts (always the same)

B

Use the symbols printed in blue on the keys.
G

Ctrl + Alt + Shift → Gray symbols

Use the symbols printed in gray on the keys.
Pro tip: keep Ctrl + Alt held down to type several symbols in a row.

Hardware (Keyboard)

Power & sleep

Turn the keyboard ON using the physical switch. It automatically enters sleep after about 10 minutes of inactivity.

Math Mode is controlled in the Windows app: double-click the tray icon (or use Ctrl + Alt + Shift + F12) to toggle it ON or OFF.

Keyboard OS mode (important)

Make sure the keyboard is set to the correct OS mode so the keys behave as expected.

Fn + Q → Windows mode

Use this for the Windows app and the math shortcut layers.

Fn + W → Mac mode

Use this when you want standard Mac key behavior.

Connectivity

Choose your connection mode

The keyboard can connect in 2.4G mode using the USB receiver, or in Bluetooth mode. For Bluetooth, the first connection requires entering pairing mode manually.

2.4G = fast plug-and-play wireless setup
Bluetooth = pair once from your computer settings

    Use a direct USB port if possible.
  • 3

    Press the 2.4G button on the keyboard

    The 2.4G indicator should light up, confirming that 2.4G mode is selected.
