Hands Down
34-key Ferris Sweep keymap on Hands Down Vibranium with an alpha thumb. Magic keys finish whole words from context (b+magic → because); adaptive keys rewrite same-finger bigrams into rolls (n+r → ng, l+r → ll). Low finger travel, in-roll bias, arrows reachable from the home row. No home-row mods — timing-robust, no tap-vs-hold misfires.

QWERTY
Yet another crkbd keymap which has emerged from a combination of writing and programming using Emacs on MacOS and Linux. The numeric layer has numbers on the home row and shifted symbols on the first row, with commonly used brackets on the third row symmetrically between sides. The emacs layer(s) provide both command and prefix keys.

ЙЦУКЕН, QWERTY
A minimalist keyboard that emerged as a symbiosis of the ideas of the Gherkin and Katana60 keyboards. Gherkin is bad because it is impossible to use when you add a space since it takes up the usual lower row of characters. Katana60 is good for everything except that it is expensive and not made by me.
