SliceMK has an ErgoDox variant that is wireless and low-profile using choc v1 switches. Disclaimer: I've been daily-driving one of their ErgoDox Wireless Lite keyboards for about 9 months. But I like the ErgoDox physical layout -- been using one on a nearly daily basis for the past 9 years.

ErgoDox wireless from SliceMK (https://www.slicemk.com/pages/ergodox-wireless) is my suggestion. My current daily driver is a ErgoDox Wireless Lite -- been using it for about 10 months now. The guy behind it (series of wireless ErgoDox variants) is very helpful with problems on his discord. He also has a webUI configurator that works reasonably well (which I don't use because I prefer to keep my configs in git).
A quick duck search pointed me at https://toolsweek.com/how-to-test-a-diode-with-a-multimeter/ . It's been a long time since I needed to test diodes, but the instructions seem to match what I've done before.
If you choose SPC < to bring up the window that shows all open buffers, you can choose it and hit SPC b k (buffer, kill) as !GameWarrior@lemmy.world suggested. You can also choose SPC b d (buffer, delete) which is the same as SPC b k, or just hit SPC b and look at the options available to you.
+1. I've standardized on 3 thumb keys per hand across all my keyboards.
