Your Recommendations for Corded Keymappings (e.g. Techinques and/or Software)
While I'm particularly looking for chords (ex: if jkl; are all keydown at the same time then send the space keypress) I'd be happy to hear about your keymapping approach in general. E.g. how do you organize your layers, have you needed to custom compile anything, mapping choices you regret but are too hard to change now, etc.
I got my first ergomech board recently. I've got the background to flash the board manually and code everything in C. But before I go down that very deep rabbit hole, I wanted to see if what others had done/learned.
Personally I'm not planning to go full asetniop with cords. I think I just want a handful of chords to go along with layers.
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 been using Miryoku for almost a year now, and I love it. The home row mods became natural surprisingly quickly. I do still need to tweak a setting somewhere; I tend to leave accidental "j"s around when I get found fast and an going for a capital on the left hand.
Here's my keymap. This image is ever so slightly outdated but should give you a decent idea for my keymapping. If you have questions feel free to lemme know.
It took a lot of work to get it here, lots of trial and error and moving stuff. I have my combo timeout really low so that changed what I could use for combos.
