This mod clearly indicates which keys should be pressed by each finger when touch typing using RGB. This is to help touchtyping beginners use the correct finger on all keys.
E.g. For the J keys, the keys 6, 7, Y, U, H, J, N & M are all highlighted red which indicates that all of those keys should be pressed by your index finger. This helps you to better distinguish which keys are for which finger so you can learn to touchtype without incorrectly using the wrong fingers.
This mod has 2 modes:
RGB (Default) - Uses multiple different RGB colours to indicate the keys, making your keyboard still look "gamer" while you're learning.
KeyBR - A simple version using just White, Green and Orange to indicate the colours which replicates the demo keyboard on the KeyBR website.
To use the KeyBR version, turn all layers off except the ones that say KeyBR, and to use RGB, switch everything on except KeyBR.
