Seems like a silly solution but so just use evtest to disable the keyboard. Did a tiny bash script to disable and re-enable the keyboard by just tracking the pid

I got mine used and in the bag of shame raffle 😅 AUD to USD makes them pretty expensive. They are really nice though. If you’re on the fence I’d get some printed in MJF and use those for a bit. )Then you’ll fall in love with the profile and be forced to buy the real deal hahaha )

I like DES for mx and it works well for combos as well. You can buy a set from Asymplex if you have the cash. Or order them from JLCPCB in MJF which is also pretty nice. You can find pre spued files for that on GitHub if you search around

Vertical Combos are pressed with a single finger. Possibly easier depending on keycaps and key spacing (choc spaced and Chicago Steno is what I use). You basically press in the crack between the two keys pressing both at once.

The horizontal combos are done with multiple fingers. You can see the blue keys on the base layer as well as the combo diagrams on the bottom for the rest of the combos.

KeymapDB is great and I believe they have a combo/chording filter to look at keymaps that use them.

I’ve got quite a few combos on my keymap while still typing in a standard way. More combos than keys haha keymapdb.com/keymaps/grassfedreeve/

If you’re looking at red pro, I’d go for ambient twilights the new silent switches are improvements in every way for linears.

Showing it in its natural habitat hahaha

26-key, column-staggered, wireless, reversable, split keyboard made with Ergogen and KiCad github.com/grassfedreeve/pueo/

For a silent and portable keywell you’ve basically only got the Glove80. Their new Cherry Blossom silent switches is where I would go. Voyager is also ann option but only slightly less expensive than the glove and you lose the keywell. I’d definitely go for that if you’re willing to drop the cash. There’s usually a few used ones up for sale on the MoErgo discord
