dizygotic keyboard

This one, it should be straight, not bent. Because the idea with number pad in the middle, is that it should solve most of the wrist bending problem without being split or tented. Straight form makes it simpler and easy to carry. If you gonna have a bend angle a little, might as well angle all the way and not have numpad in middle idea.

Do research to find out all non-ASCII chars used in other langs. Their frequency. Consult the NEO layout [see German Keyboard Ergonomic Layout], Bépo Layout [see French Keyboard Ergonomic Layout], Portuguese: pt-Nativo etc. The goal is to create a letter layout such that it is more efficient to type frequently needed non-English letters but more efficient than any local layout, for the top 5 most popular languages.
