摘要:
A stenographic machine includes a keyboard having a first area containing keys designated for at least some of numerals "1", "2", "3", "4", "5", "6", "7", "8" and "9", a second area containing keys designated for consonant letters, a third area containing, in order from left to right, keys designated for vowel letters "A", "O", "E" and "U", a first additional key designated for numeral "5" and a second additional key designated for numeral "0". The additional keys are located elsewhere than in the first area and are preferably directly below the keys designated for the letters "A" and "O".
