From the project
It's a keyboard family which based on my circumstances, preferences, and observed usages.
It's a keyboard family which based on my circumstances, preferences, and observed usages.
- 5 columns per hand. My right pinky is almost useless. - At most 3 keys for each side's thumb row. My right thumb key is almost useless. - No numrow. It's harder and more cumbersome to use than a numpad on a layer. - Split. Typing on single flat keyboard hurts my arms in a lot of use cases. - Symmetric. Personal preferences.
