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.

On the typewriter, the Caps Lock key is not a toggle key. Pressing the key does not switch between states. No matter how many times you pressed the key, the end result is the same; caps-locked.

When you pressed the Caps Lock key, it remained physically depressed. You could see and feel that the typewriter was in caps-locked mode. The best the keyboard provides is indirect indication with a LED lit in the corner of the keyboard, amidst an array of other LEDs.

On the typewriter, the caps lock mode was very transient. Pressing either Shift key would release the caps lock. A typist that did not notice a caps-lock state would automatically be released from this mode as the shift key is pressed to begin the next sentence. As such, tHE eRROR oF tYPING lIKE tHIS never occurred on the typewriter.

The design of the typewriter Caps Lock key seems to consider human behavioral norms. The keyboard abuses these behaviors. There are no logical reasons for the keyboard not to follow the design patterns set forth by the typewriter. On the contrary, the keyboard brought an opportunity to improve upon the design. It is a shame we are still stuck with the results of this wrong turn.

To deactivate the irksome Caps Lock key on X.org, XFree and presumably other X11 servers, the xmodmap utility is used to remove the Caps_Lock keysym from the lock modifier class:
xmodmap -e "remove lock = Caps_Lock"
The xmodmap utility unbinds the Caps Lock key from the lock modifier class temporarily, thus it needs to be executed every time you restart your X session.
To save the changes permanently as the global default, append the xmodmap expression to your global Xmodmap file (usually /etc/X11/Xmodmap). To save them only for your own user, append the expression to your ~/.xmodmaprc file.

How to reconfigure the Caps Lock key on X.org/XFree to do [insert action here]?

There are several actions people would like the Caps Lock key to perform instead of doing the Caps Lock, suggested are (among others) another Ctrl key (Happy Hacker layout) or a second Backspace or Enter key. We assume you already unbound your Caps Lock key from the lock modifier class as described above ("How to deactivate the Caps Lock key on X.org/XFree?").
The key can easily be transformed to another Ctrl key by adding it to the control modifier class: xmodmap -e "add control = Caps_Lock"
To transform it to a second Enter/Return key, overwrite the Caps Lock key's keycode with the Return keysym (keycode 66 on common keyboard layouts): xmodmap -e "keycode 66 = Return"
If you want it to become a second Backspace key instead, replace the Return keysym name in the example above by BackSpace.
