I’ve seen a few keyboards from other countries (including Japan and England) but typically the letter layout is fairly consistent.
There has been talk of putting the vowels all together and doing other things to radically change where each letter is.
And that “L-shaped” enter key in the 1990s slowed us down typing network paths (the “\” key moved and where it was had been swallowed up by the Enter key). Mistype the keystroke and you’ve entered only a partial path.
The standard German keyboard layout resembles the standard U.S. layout - but the "y" and "z" are transposed (for good reason, too!), and then there are also the "ö," "ä," "ü," and "ß" not found on U.S. keyboards.
(According to Kurt Vonnegut Jr. in "Mother Night," some older German typewriters had additional special symbols like a runic double lightning stroke, for some reason.)
Of course, there is virtually no correspondence between Russian keyboards and U.S. ones.
