@szajbus @frigidcode I like it because it gives me 2 extra keys within easy reach.
This keyboard uses QMK which is a programmable firmware on the keyboard itself, so any re-maps / layers are persisted across computers without installing software (because the keyboard itself is actually sending whatever keycode, which is awesome if you have multiple computers or an incredibly locked down work computer where you're not allowed to install software or remap keys)
I use the FN button in the middle as a "up one layer" and the right space as "down one layer" to easily swap kb layers without moving my hand a lot.
