its the custom firmware that does it, the layout and layers I just made up as I needed them but its flashing the firmware every time I want to change something. There are other keyboards and keyboard firmwares that can do this, I use qmk, and its possible to mod normal keyboards to varying difficulty. The keyboard I have is a semi diy that came as a kit but there are others ready to use but still customizable in firmware. I think there was also another kb firmware that let you live edit the layouts without flashing firmware using a config software but I haven’t looked in to it.
