Chocofi 36 with QMK

The keyboard

https://github.com/pashutk/chocofi/

I got a prebuilt one with hotswap and seapi picro presoldered and added my choc v1 brown switches.

The Keymap

Since a lot of time is spent navigating code I use a locked NAV layer, which makes it easy to move the cursor/screen. Most of my time coding is spent in VSCode. Therefore, often used combos like Ctrl+f, Ctrl+h (find an replace) and their shifted variants (find/replace in project) are available in the NAV layer with single keystrokes.

Setup

1. follow QMK initial setup (python venv with pip)
2. link this directory into qmk_firmware/keyboards/crkbd/rev1/keymaps/choc_colemak_36
3. compile and flash assumes right usbc is connected

  cd ~/src/qmk_firmware/ && source env/bin/activate
  qmk compile --keyboard=crkbd/rev1 --keymap=choc_colemak_36 -e CONVERT_TO=promicro_rp2040
  sudo mount /dev/sdb? /mnt/
  sudo cp crkbd_rev1_choc_colemak_36_promicro_rp2040.uf2 /mnt/
  sudo umount /mnt

TODO Missing stuff

• Shift for right hand
• Ctrl for left hand
• Alt on base layer
• backtick key
• umlauts and sharp s
• euro € key

Ideas for improvement

• for nav layer, maybe add combined keys for Ctrl+Shift, Ctrl+Alt and Shift+Alt
• this seems like a great example of composed layers and support for different environments https://github.com/0x64746b/qmk_firmware/blob/chocofi/keyboards/chocofi/keymaps/dtk35/keymap.c
• https://github.com/qmk/qmk_firmware/blob/master/layouts/community/ergodox/german-kinergo/keymap.c#L101

• split up SYM_NUM layer, move missing symbols (from NAV layer to SYMBOLS layer)

  • hints for better symbols layers: https://getreuer.info/posts/keyboards/symbol-layer/index.html
  • make . and , available in new NUM layer for easier number input

• build a dedicated GUI Nav layer for i3wm/sway

  • and probably Windows/KDE window actions
• make select words work (by emulating Ctrl+Shift+Left/Right)
