They’re just keys - you can remap the middle ones to be your enter, tab, backspace and escape. That’s basically what I do with my Planck layout. https://github.com/qmk/qmk_firmware/tree/master/keyboards/pl...
For my personal mix of tendon and joint problems actual separation isn’t helpful because some pronation is actually good for me. But obviously that’s going to vary.
Nice laptop keyboard.
