First, a thank you to Hasu for his tremendous work. Within hours I was able to follow the documentation to solder and program an arduino Pro Micro to act as a USB adapter. I nearly fell of my chair when it actually worked. So amazing - thank you to everyone who participated in the documentation as well.
My question is about the keymaps - I've seen the bit
https://github.com/tmk/tmk_keyboard/wiki/FAQ-Keymap#esc-and--on-a-key about HHKB style handling of Escape and Accent Grav / Tilde (where shift + ESC = tilde, FN + ESC = ` and just hitting ESC is escape).
I would additionally like ESC to work as `/~ when LGUI (or LGUI+Lshift) are held, as that's the mac shortcut to cycle and reverse cycle windows within an application. Of course each should work normally independently, as well as together with other keys and shortcuts.
Suggestions (or a link to a keymap) welcome - I tried expanding the idea
