> Stenographers stroke chords instead of typing keys, resulting in less movement and better ergonomics than typing. over the years I've seen various chord-style keyboard schemes. I've wondered why none have caught on - seems more logical than hitting individual keys.
Think about all the people you know that still have to look at the keyboard to type, that type just using one finger and one hand at a time, that still hunt for common symbols. None of this would work with a chording keyboard.
Unless you're transcribing, typing is not usually a limiting factor. This is especially true for programmers. For example I'm using three different keyboard layouts due to the commonality of languages around here and as a result I keep doing typos due to switching. I never bothered on improving because it's simply not a limiting factor.
What's even more ironic to me, is that we would have much simpler improvements to keyboards to make RSI and typing more efficient with minimal impact (I'm thinking ortholinear layouts - not chording!), but nobody really seems to care.
