I'm surprised that there seem to be no examples anywhere of anyone seriously using chorded typing for programming. After cheap chorded keyboards entered the market and the associated software became free, I assumed it would only be a matter of time before something like Travis Rudd's incredible demo of voice coding [1] came out. Perhaps that it hasn't speaks to how difficult it is to get real speed improvements with a chorded setup?
