emacs keyboard: μTron keyboard
updated the emacs keyboard μTron keyboard.
This is a excellent design. The only design issue i found is that it doesn't have dedicated function keys. The function keys are merged with the number keys. However, the other quality design makes up for it. (For why dedicated function is important, see: Function Keys in Computer Keyboard. For why the μTron is a excellent design, see: Keyboard Hardware Design Flaws.)
