Actually, I'm going to have to amend my answer to the revised answer of:

****** Actually, bonanova, your keyboard, I'm sure, does not look quite like that. For instance, the "Q" key
is not perfectly adjacent diagonally to the "S" key. And, for instance, the "W" key is not perfectly adjacent diagonally
to the "D" key.
To go from Q to S in the shortest path, you must pass through either A or W.
And to go from W to D in the shortest path, you must pass through either S or E.
You just look more closely and you'll see that the top row is not in line with the middle row, I'm sure.
