Your hands never leave the keys.

A split mechanical keyboard with a thumbstick on each half. The halves sit apart on a desk, or join into one and hang at your chest on a strap. The cursor and the scrolling are under your thumbs, so there is no mouse to reach for.

KEYS: 65, split, column-staggered
THUMBSTICKS: One on each half
TILT: 8° forward, 20° to the side
LAYOUT: MacBook (US), key for key

FIG 01 // MACBOOK LAYOUT

65 keys,
each where your MacBook has it.

Many split keyboards drop to 36 or 42 keys, and numbers and brackets move onto layers you have to learn.

Keythra keeps all 65 keys of a MacBook keyboard in the same places, so the shortcuts and the number row your fingers know are still where they were.

Keys, as on a MacBook: 65
Number keys in a row of their own: 10

Command and Option where you expect them

On a MacBook your left thumb rests on Command and Option. Keythra puts both in the left thumb keys and the bottom row, so ⌘Tab, ⌘Space and ⌘C / ⌘V work as they always have.

MacBook keyboard: ⌘ Command + ⌥ Option
Same keys, same places: Same keys, same places
Keythra, 65 keys: Left thumb keys (⌘ / ⌥)

FIG 02 // GESTURES

Two sticks.
Tilt them together,
and the windows follow.

Up and down are the same on both sticks; left and right are mirrored. Tilt both at once to open the task view, the app drawer, the desktop or search, with no shortcut to remember.

Task view / Mission Control

Spreads out every open window. Tilt the left stick to pick one.

Interactive dual-stick keyboard simulator. Focus this area to use its keyboard controls.

FIG 04 // POSTURE

Shaped for the body.
The desk is optional.

A flat keyboard keeps you leaning over a desk. Keythra goes where you are: worn at the chest, resting on the armrests, or on the desk with each half tilted.

Worn at the chest

Join the halves and hang them on a strap. You can type standing up or walking about, with no desk under your hands.

On a strap

Your arms hang from the shoulders instead of reaching forward to a desk.

Leaning back in a chair

Rest one half on each armrest and lean back. Typing, scrolling and moving the pointer go on as usual, without sitting up to a desk.

On the armrests

Each half rests on its own, as far apart as your armrests are.

Tilted 8° forward and 20° to the side

Each half has a fixed tilt, 8° forward and 20° to the side, so your hands rest closer to the way they hang when relaxed.

8° / 20°

Your forearms do not have to turn flat, so the wrists stay more relaxed.

FIG 05 // BUILD

Built for daily use.
Switches you can change yourself.

Two analog thumbsticks, standard hot-swap switch sockets, and a shell shaped around the fixed tilt.

BLOCK 01

A shell shaped around the tilt

The halves are shaped from physical prototypes, and line up edge to edge when joined into one.

8° / 20° tilt

BLOCK 02

Two analog thumbsticks

The further you tilt a stick, the faster the pointer moves or the page scrolls. Tilt both together for the gestures.

One on each half

BLOCK 03

Standard MX hot-swap sockets

Change switches without soldering. The sockets take standard full-height MX switches with 3 or 5 pins.
