- If you had bothered to read other messages, or even knew anything
- about mechanical typewriters, you would know that E and D *are*
- "horizontally" adjacent in the only place it counts: the hammers. The
- reason the keys are "staggered" on the keyboard is so that the
- mechanisms for four consecutive hammers can easily be attached to keys
- on four different rows. E and S, however, are separated by 3 and X.

- No, E and R are separated by D, 4, and C, so are a lot less "jammable"
- than the E-D combination. They are also a lot more frequently paired
- in English usage. In fact according to authority (Abraham Sinkov,
- Elementary Cryptanalysis, MAA 1966) the digraphs ER and RE are the
- fourth and fifth most frequent in English usage, after TH, HE, and
- IN, and together are more frequent than any other such letter pair.

- I would not have responded at all to your post, since others have
- convincingly argued that the designed-to-be-slow theory is false,
- except for the way you combined your "facts" with this supercilious
