Matias Ergo Pro Keyboard
Note, as of 2018-12-15, this keyboard still seems to have key repetition problems. There are a lot alternatives now.
Matias came out with a mechanical ergonomic keyboard, on 2015 July.
This is excellent.

Excellent features:
- Mechanical keys. [see Mechanical Keyboard and Repetitive Strain Injury]
- Split design.
- Big Ctrl key, big Alt key.
- Modifier placed close to thumb. Note the Alt (or β command) is between X and C. (on a typical computer keyboard, it's between Z and X. For example, see: Logitech G710+ Keyboard)
- Split space bar. Excellent!
- Dedicated keys for undo cut copy past. Excellent!
The key switch used is a βALPS-inspiredβ. [see Keyboard Key Switch Mechanisms]

There's a innovation here. Note the Ctrl key, above the right space key.

Problems
- Key repeat or not register. Many amazon reviews complain about this.
- The keyboard is bulky, with large margin.
