I've made a subtle yet significant modification to the classic Corne keyboard. I've incorporated additional features to take the Corne keyboard beyond, adding 2 encoders, a joystick, and bringing back 6 buttons, this it's only a funtional prototype but hopefully someday I'll be able to desing a proper board and case.
This is a keyboard designed for a macOS environment with a Dvorak layout, so most of the mappings are only for macOS and use Dvorak bindings, yet it's more interesting funtions are available on any OS and layout.
Here's a link to a video demo(Youtube)

This keyboard is focused on macOS with Dvorak Bindings. Saying this for some reason, on a Dvorak layout, the keys get physically mapped. For example, the copy shortcut uses cmd + c on a QWERTY layout. There's no problem; you just map it normally as LGUI(KC_C). On the other hand, on a Dvorak layout, you should map the physical place of C on the layout, which is I. So that's why I mapped LGUI(KC_I).
Most of the universal ones should also work fine on Linux and Windows using the Swap Control and GUI magic code feature available on the 5th layer as CG_SWAP key. However, for macOS, that won't be useful at all on other OS.
| Shortcut | macOS | QWERTY | Dvorak | Compatibility |
|---|---|---|---|---|
| Select | cmd + shift | LGUI(KC_LSFT) | Same | All |
| Select All | cmd + a | LGUI(KC_A) | Same | All |
| Cut | cmd + x | LGUI(KC_X) | LGUI(KC_B) | All-check |
| Copy | cmd + c | LGUI(KC_C) | LGUI(KC_I) | All-check |
| Paste | cmd + v | LGUI(KC_V) | LGUI(KC_DOT) | All-check |
| Undo | cmd + z | LGUI(KC_Z) | LGUI(KC_SLSH) | All-check |
| Redo | cmd + shift + z | SGUI(KC_Z) | SGUI(KC_SLSH) | All-check |
| Comment Line | cmd + / | LGUI(KC_SLSH) | LGUI(KC_LBRC) | All |
| Save As | cmd + shift + s | SGUI(KC_S) | SGUI(KC_SCLN) | All |
| Save | cmd + s | LGUI(KC_S) | LGUI(KC_SCLN) | All |
| Tab Left | cmd + alt + Left | LAG(KC_LEFT) | Same | All |
| Tab Right | cmd + alt + right | LAG(KC_RGHT) | Same | All |
| Back | cmd + left | LGUI(KC_LEFT) | Same | All |
| Forward | cmd + right | LGUI(KC_RGHT) | Same | All |
| Zoom in | cmd + - | LGUI(KC_MINS) | LGUI(X_QUOT) | All-check |
| Zoom out | cmd + + | LGUI(KC_PLUS) | LGUI(X_RBRC) | All-check |
| Close Tab | cmd + w | LGUI(KC_W) | LGUI(KC_COMM) | All-check |
| Tab Nav | cmd + Tab | SGUI(KC_TAB) | Same | All-check |
| Shortcut | macOS | QWERTY | Dvorak |
|---|---|---|---|
| Print Screen | cmd + shift + 3 | SGUI(KC_3) | Same |
| Custom Print Screen | cmd + shift + 4 | SGUI(KC_4) | Same |
| Mission Control Up | ctl + up | LCTL(KC_UP) | Same |
| Mission Control Down | ctl + down | LCTL(KC_DOWN) | Same |
| Mission Control Left | ctl + left | LCTL(KC_LEFT) | Same |
| Mission Control Right | ctl + right | LCTL(KC_RGHT) | Same |
| Switch App Window | cmd + ` | SGUI(KC_NUBS) | Same |
| Up a Folder | cmd + up | SGUI(KC_UP) | Same |
| Open Folder/Files | cmd + down | LGUI(KC_DOWN) | Same |
| Search | cmd + space | LGUI(KC_SPACE) | Same |
| Delete | cmd + Backspace | LGUI(KC_BSPC) | Same |
Also, check the mapping you get with these keys; I think they change across the OS. On macOS, you get this:
KC_NUBS = ` KC_GRV = §
- Corne Keyboard.
- All or some of the electronic components on the list.
- At least Qmk firmware version 0.21.1.
To compile and flash from the qmk setup folder, copy the 'Code' folder to your
local qmk folder and place it into keyboards/crkbd/keymaps then run:
$ qmk flash -c -kb crkbd/rev1 -km Code
- Alternatively, you can also just flash the firmware
and should be working fine.
- The firmware size is approaching the maximum - 28470/28672 (99%, 202 bytes free)
- Check the diagrams
- Check the Qmk configurator
This is the list of the electronic components required:
| Component | Quantity |
|---|---|
| Nintendo Switch Joystick (Or a PSP or PSVita Joystick) | 1x |
| Tripod Thumbwheel Toggle Switch | 2x |
| Kailh 7mm Rotary Mouse Scroll Wheel Encoder | 1x |
| Rotary Encoder Module for Arduino | 1x |
Check the layout photos and the layout for the QMK configurator. I was not able to add the extra keys but still, I think it would give you a good idea of how the layout is mapped.
If you want to get back the RGB feature, you can disable one or more features:
Joystick: Delete these lines in 'rules.mk':
- SRC += analog.c
- MOUSEKEY_ENABLE = yes
- POINTING_DEVICE_ENABLE = yes
- POINTING_DEVICE_DRIVER = custom
Encoder: Delete this line in 'rules.mk': ENCODER_ENABLE = yes
Lag algorithm: Delete this line in 'rules.mk': DEBOUNCE_TYPE = asym_eager_defer_pk
And modify these lines:
- RGBLIGHT_ENABLE = yes
- RGB_MATRIX_ENABLE = yes
For some reason, when I use the keyboard on macOS with a Dvorak layout, I must change the mapping to match the keys' physical positions instead of the literal bindings.
Example:
Copy binding on a QWERTY macOS layout should be: cmd + c, but because of this strange behavior, I wrote cmd + i where 'i' is the place on the physical keyboard for c. So, in the end, it's written LGUI(KC_C) instead of LGUI(KC_I).
- Detect the host OS and automatically use swap Ctrl/GUI
- Use smart zoom on macOS (I think it's not possible because it's reserved only for the trackpad)
