Please make keyboards with the "stroke directions" lined up for the directions the fingers actually move. On a standard keyboard, the right fingers will stroke up and to the left, or down and to the right, which is the direction that the keys run. However, the fingers on the left hand want to stroke up and to the right, but the keys for the left hand stroke up and to the left.

This may have made sense 100 years ago, when typewriters were first created. Given the new improvements in manufacturing over the last century, this no longer makes manufacturing sense, and never made body-mechanic sense.

Additionally, this will force the keyboard to be wider — in particular, it will force the "rest" or "home" position of the hands to be slightly farther apart, further helping body mechanics.

Finally, although "seperated" left and right half keyboards make a lot of sense — especially with "wave", curved/raised layouts, please please please duplicate the "b", "y", and "6" keys — currently "assigned" to finger strokes that are often easier to make from the other hand — on both sides of the keyboard. Thank you.
