I can only imagine how much hairier these diagrams become if generated from code instead of English/html. Even for the best case scenario of "The Robot" combined with an "ergonomic" layout like dvorak or colemak, the right pinky area would be a tangle of deep purple. If the diagrams were updated to include backspace key usage, the mess only gets worse. I couldn't find a typing tutor that addressed the difficulty of typing the symbols in code, so I created a webapp called http://typing.io http://typing.io. It allows programmers to practice typing open source code instead of English or drills.
