Dvorak keyboard?

The lino keyboard actually had vertical rows of each letter in different sizes.

ETOIN SHRDLU are the letters in the two right vertical rows. The machine I worked on only had four or five lower case "i" matrices, so if you came across a line with the word "initiation" in it, for example, you had to rewrite the rest of the line. You were flat out.

If for some reason the operator had to produce a couple of slugs for the end of a story, he might simply run his finger down the right hand row of keys -- whoever said this was faster than a typewriter was right about that, it could drop matrices in sequence no matter how fast you ripped a finger across the keys. The result was:

ETOIN
SHRDLU
