英语词汇etaoin shrdlu的起源、历史背景-英语词源词典

词汇	etaoin shrdlu
词源	etaoin shrdlu 1931, journalism slang, the sequence of characters you get if you sweep your finger down the two left-hand columns of Linotype keys, which is what typesetters did when they bungled a line and had to start it over. It was a signal to cut out the sentence, but sometimes it slipped past harried compositors and ended up in print. Entries linking to etaoin shrdlu qwerty in reference to a type of non-alphabetic keyboard or key arrangement, by 1925, from the first six keys on a standard typewriter keyboard read as though text from upper left. Mechanical typewriters were patented from 1867; the QWERTY layout itself is said to date to 1887 and became dominant in U.S. from early 20c. It is meant not to slow typists, as sometimes is said, but to separate the letters in common digraphs (-sh-, -ck-, etc.) to reduce jamming of swing-arms in old-style machines. It actually speeds typing by requiring alternate-hand strokes, which is one reason the alternative DVORAK keyboard is not appreciably faster. Remnants of the original alphabetic typewriter keyboard remain in the second row of letter keys: FGH-JKL. The French standard was AZERTY; in Germany, QWERTZ; in Italy, QZERTY.
