In the 1930's, when a private-eye wrote an investigative report it was done on a typewriter. There was no software, no computers and if you did a typo, you pulled the paper out and started over. When typewriters first came out, people learned to type so fast, they would jam the keys that popped up. To solve this problem, the keyboard was the scrambled so people would type slower so the keys would not jam. We still use the same keyboard layout of the letters today. If you look at the first row of letters on your keyboard, it spells typewriter scrambled.
