2. How to map mac keys to a Windows keyboard

If your keyboard only supports Windows by default and you want to set it up for Mac, follow the tutorial below.

Take Lemokey P1 Pro as an example, the default layer is Windows, with Layers 0 and 1 for Windows keys and Layers 2 and 3 blank. To set up for Mac, customize Layers 2 or 3.

Click 'Keymap' on the left, and click on the key that you want to program, and the key will be marked with a red box. Click on a key you want to remap in the Basic/ Media/ Macro/Special/ Lighting/ Custom/ Layer section. And it's done. Here is a video example.

3. Set Your Own Shortcut Keys to Quickly Switch

After mapping the keys and setting up the Mac layers on a single system keyboard, the TG(n) function allows for quick switching between the two systems. Next you will see how to set the TG(n) function and more details about it.

How to set TG(n)

After your keyboard is connected to the Launcher, click the 'Keymap' button on the left, then click the 'Layer' button. And click on the key you want to set to TG(n). Here is a video example.

TG(n): Toggle layer on or off

How to use it:
Assign TG(n) to a key to switch between your main layer and layer n (e.g., for the default Windows layer and Mac layer). Press the key once to activate the layer, and press it again to turn it off.

Example:
Suppose Layer 0 is your default layer and layer 2 is Mac layer. Assign TG(2) to Fn. Press Fn once to activate the layer, and press it again to turn it off.

On the Keychron Launcher web app, we have other function keys for quick layer switching, they are MO(n), TT(n), OSL(n), TO(n), DF(n).
