“I found that on a computer keyboard, there are combinations of letters and words that I scream through, and it cant be done on a regular typewriter that way...you have to be more consistent.”
The arrangement of the keys (QWERTY) was an attempt to put the most-often-typed-together letters far enough apart so as to slow down the typist and avoid jams.
The arrangement of characters on the QWERTY keyboard was to speed up transcription from American (not International) Morse.
