See, when people started typing they would go so fast that the mechanical keys would jam up on top of each other a cause the user to untangle |
Actually it's a simple mechanical problem....the keys were set so that the likelihood of conflicting [tangling] keys was reduced.
It was nothing to do with the speed of 'typing'...but the simultaneous double keystroke [of any combination] that could cause a clash...in other words...the speed of hitting keys, not the speed of textual, grammatical typing.
The mechanics of a 'hammer' keyboard were always a limiting factor to typing speed, no matter how obscurely the keys were placed, hence the later adopted daisy-wheel and 'magic ball' systems that restricted the typist to one key at a time....no matter how fast he typed.
The reality is that no matter what order the keys are placed most synchronous keystrokes will jam them...
