Think back to a MECHANICAL typewriter (Score 3, Informative)

On a mechanical typewriter, the levers were arranged in strict left-to-right order, ignoring the row.

That is, the actual order was 1QAZ2WSX3EDC4RFV... well you get the idea. Keys on the same row were four levers apart, much reducing the risk of jamming.

You can still find a few common letter combinations, but you should be looking up/down rather than left/right.
