Split Keyboards and Why They Are Cool
2026-03-28 Tags: technology
I have a columnar programmable split keyboard with thumb clusters and swappable mechanical keyswitches and keycaps that I love:
Split is great:
- Placing them shoulder width apart is much more ergonomic for your shoulders, letting you sit up straight with your shoulders back.
- Angling them separately allows a natural straight wrist position, especially for people with big hands like me.
- Tenting them (angling them up towards the center) allows your wristbones to rotate less.
- You can put a coffee mug or a mouse in between them.
Columnar is great:
- Instead of staggering the keys (a relic of typewriters, which needed room for the levers beneath the keys), placing them in columns allows your fingers to travel straight up and down between rows.
- You can also lower or raise each column based on the length of the fingers (mostly lowering the pinky key, mine could go even further).
Programmable is great:
- You can add layers (basically like extra shift keys that change what each key does) to place keys closer to the home row, avoiding finger travel and contorting your hands as much.
- If you want to, you can swap out QWERTY for a more efficient layout, or create custom layers and macros for your programs (think shortcuts in editing software).
- You can also have combinations of keys trigger custom behavior, though I mostly avoid this.
Thumb clusters are great:
- Your thumbs are some of your best fingers, why should they take turns only pressing a giant space bar?
Swappable keyswitches and keycaps are great:
- Mechanical keyswitches just feel really satisfying and provide physical feedback so you know when the switch activated.
- You can choose from quiet smoother ones to tactile clicky ones to loud thocky ones.
- I started with Cherry MX silent red keyswitches and switched to tactile blues. Semira was very understanding with the noise.
- I started with flat keycaps that came with my keyboard, which allow moving them all around arbitrarily,
but switched to sculpted keycaps that lovingly cradle my fingertips.
- Since each row in sculpted keycaps have a different angle, they only work if you keep each letter in the default row supported by the seller, or by buying blank keycaps or adding stickers.
