* 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

#+begin_src bash
  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 
#+end_src

** 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/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)
