Key Points

Key Takeaways

  • 1

    Unlearn to Type

  • 2

    Split Layout: By splitting keyboard left and right, can open chest and type in natural posture. Final answer to stiff shoulders and tendonitis

  • 3

    Column-Staggered: Keys are not 'Grid (Ortholinear)' but 'Shifted according to finger length'. Design to minimize finger movement distance

  • 4

    Thumb Clusters: Thumb is too strong just to hit space key. Assign Enter, Shift, Ctrl etc. to thumb to reduce burden on little finger

  • 5

    Layers (QMK): Number of keys can be small. If layer function is used, all symbols can be input without moving hands from home position

Introduction: Curse of QWERTY

For 150 years since era of typewriter, we have continued to use key layout (Row-Staggered) “Shifted slightly to left”. Why? To prevent typewriter arm from getting tangled. Electronic keyboard has no such physical constraint.

Let’s use correct keyboard based on ergonomics. Painful at first, but once used to it, can never return to chocolate bar (normal keyboard).

1. The Gateway Drug: ZSA Moonlander

iPhone of split keyboard world. Completeness is high, and setting software (Oryx) completes in browser, so even beginners do not get frustrated.

ZSA Moonlander / Voyager

*Recommended to purchase from official site. Moonlander with movable thumb module, or thin Voyager. Since it supports hot swap, replacement of switch (axis) is also free.

Amazon

Oryx Configurator

Can change keymap on web browser and burn firmware with one click. Advanced setting (Mod-Tap) like “Ctrl with long press of A key” is easy with GUI.

2. The Endgame: Crkbd (Corne Cherry)

Even Moonlander is too big. Want to reduce finger movement more. Masterpiece of 40% keyboard “Corne” is where people who thought so arrive.

  • 42 Keys : Not even number row. Numbers are input with layer.
  • OLED Screens : Display current layer and WPM (Typing Speed).
  • DIY : Basically assemble by soldering yourself, but can also buy assembled items at Yusha Kobo etc.

3. The Learning Curve: Hell of 3 Weeks

Transition to split keyboard is like “Relearning how to walk”. First week, WPM becomes less than half, get irritated and want to return to normal keyboard.

Practice Roadmap

  1. Week 1 : Correction of touch typing. Self-taught fingering (Pressing Y with right hand etc.) no longer works.
  2. Week 2 : Mastering symbol input (layer operation). Grasp feeling of switching layer with thumb.
  3. Week 3 : Return to previous speed. And notice that shoulders are not stiff at all.

4. Comparison: Ready-made or Self-made

項目 ZSA Moonlander Corne (Self-made)
Key Count 72 keys (Many) 42 keys (Tiny)
Introduction Difficulty Low (Can use immediately) High (Soldering/Build)
Portability Medium (With case) High (Fits in pocket)
Customization Switch/Cap All (Case/MCU)

Conclusion: Attachment to Tool

Professional chefs carry their own knives. Professional hairdressers use their own scissors.

For engineers, keyboard is kitchen knife and scissors. Not time to use company supply. Please build your own input interface that can be used for lifetime.
