> I would imagine you can add an F key layer pretty easily so this shouldn't be a big deal

That may be the case, but the issue I have with this is that I need, often enough, to press random F keys while not actively using the keyboard. Like for example refresh HN while eating an apple (F5). It's a pain to have to press multiple keys.

They also sell pedals, which, I guess, you could use to switch layers. I am thinking about using pedals to switch to the arrow keys layer. I wonder what other uses the pedals have?

IME the pedal is even more clumsy than pressing two keys to switch layers (I've had an advantage pro for ~15 years and am now using a planck and also building my own split keyboard to replace the planck with something more ergonomic).
