As it stands, it doesn’t look like there is one. It appears to be a recreational mathematical toy for the creator to learn things more than it is for others to play with. It’s kind of neat nonetheless.
I think I might have made different choices for the reversal calculations, but I haven’t really thought about how I’d implement those choices, nor about nigh-insurmountable edge cases, and I’m only vaguely thinking about the “c = a OP b” case, not anything more extreme. The creator may have wanted to make the same choices but found themselves forced down a different path.
Verbatim from the creator: “it is imperfect”.


Yeah. Right Control should be where Fn is for sure.
And as an ISO keyboard user, I need my right Shift key, so that Control has to be a Shift instead. On ISO, left Shift is small and right is large. For that and other reasons I use the right one way more than the left. And if that’s not possible for deep technical reasons, hard-wire it to the left one bypassing all of the trouble. It wouldn’t be the first time a keyboard did something like that.
… and what do you know, there’s a even little space there with no key where they could put the Fn key omitted by those changes.
Everything else I could deal with. Even the otherwise US layout. It’s been a while since I used one, but occasionally there’s a hiccup and I’ll reach for double quote or at-sign in the opposite places, so that muscle memory is still there, maybe waiting for mangling into typing on something like this.
