From the project

My endgame split ergo of this month

これまでに購入したり設計したりしてきたキーボードたちのアイデアを豊富に盛り込んだ、個人的に集大成のキーボードです。

- 数字行から上はバッサリカットして、コンパクトにしています - 一方で、横方向にはしっかり12列あるので、Ctrl, Shift を一般的な配列と同様に小指に置くことができます。複雑なショートカットキー (Ctrl+Alt+? など) を変わらず使用できます

- 左右に割れています - 両手に b があります - 横にも縦にもズレた、独特の左右対称配列になっています。横ズレに慣れたタイピングの癖をそこまで矯正することなく、縦ズレのフィット感を享受できます - 逆に、格子配列や縦ズレに慣れた人にとっては、最上段がホームポジションに近づき押しやすくなります（t, y 遠い問題） - 親指キーが他のキーから少し離して配置されていて、手を自然に開いた状態で届くようになっています - スタビライザーが不要です
