So, to summarize, the original typewriter layout (1868) was alphabetical, with the top row (A-N) going left-to-right and the bottom row (O-Z) going right-to-left. Then (1870), the vowels (including Y) were pulled out and put in a separate top row. After that (by 1872), changes were made in order to better support the use case of people receiving Morse code, and that's when we finally start to see something that looks like QWERTY. Additional changes later got it to the modern form, but by 1872 something QWERTY-like was in place.<p>And yeah -- if you look at the bottom two rows of a QWERTY keyboard, you can still see what remains of that alphabetical ordering, being left-to-right on one row followed by right-to-left on the row below!
