This is basically almost copy-paste from my Corne keymap with a couple of tweaks. I wanted to start from something familiar and then improve later. Some not-so-obvious choices: - Right alt has to be accessible on default layer, because I use Polish characters - Meta and left control are my Emacs buddies which should be close to me ;) I like having numbers and symbols separated, so I don't have to press three keys to get what I want. In fact, I even made custom keycodes in my qmk config for other keyboards (40%) to have symbols separate from numbers. https://github.com/szpone/faw36config/blob/main/config/boards/shields/faw36/faw36.keymap
