I believe 9753 2468 was originally part of the Dvorak Simplified design... It definitely does make some sense.
Yeah, sort of. The original Dvorak (not the "Simplified Dvorak") was
7531902468. The idea is Benford's Law, that states that not all numbers are typed as much:
So the smaller numbers (much typed) should be on stonger fingers. This is not like the standard qwerty layout in which 1 and 2 are on pinky and ring finger.
The layoutidea from Mtgap takes Dvorak' s idea further:
1 and
0 are on the home row, the other numbers are on the Q row (= closer than the numbers row) and other numerical characters, such as
= + : () and so on are easy to type.
Hmm.... I may even try this one out myself!
