I have some time to try and work on this. I'm hoping to lay out a PCB with switches in the right locations to drive 7bit's keyboard (more or less). I have found the tools somewhat hard to use, but I'll give it a shot.
I'm a bit worried about keys with stabilizers, as I'm not sure where to get those.
Recreating the Lisp keyboard

It's cool, although I haven't really finished the project. My wife's reaction to the noise the keyboard makes was quite funny, but I suspect if I keep using it, it will become less so.
I'm worried that it will be hard to switch between a Symbolics keyboard and a laptop keyboard. I also don't know what to do with both BACK SPACE and RUB OUT keys, or with both RETURN and LINE. But certainly, a lot of those problems can be solved with firmware. I've modified hans23's firmware a bit, partly to make it work with the newer Teensy boards. I have not yet fixed the layout to work to my liking.
BACK SPACE is like Backspace and RUB OUT is like Delete.
RETURN is just like you Enter key, while LINE is RETURN+TAB.

My idea was to use 2 switches. Maybe those 2 switches should have a lighter spring inside.
For keys up to 1.75 units, no stabilisers are needed.

Ah! Thank you! I don't know why I didn't parse it that way before, but I think I get it now.
I am pretty sure that's not my ideal layout, but that's why firmware is firmware and keycaps come off.

OK, that's a very workable plan.
