Text Input
Written Japanese uses several different scripts: kanji (Chinese characters), 2 sets of kana (phonetic syllabaries) and roman letters. While kana and roman letters can be typed directly into a computer, entering kanji is a more complicated process as there are far more kanji than there are keys on most keyboards. To input kanji on modern computers, the reading of kanji is usually entered first, then an input method editor (IME), also sometimes known as a front-end processor, shows a list of candidate kanji that are a phonetic match, and allows the user to choose the correct kanji. More-advanced IMEs work not by word but by phrase, thus increasing the likelihood of getting the desired characters as the first option presented. Kanji readings inputs can be either via romanization (rōmaji nyūryoku, ローマ字入力) or direct kana input (kana nyūryoku, かな入力). Romaji input is more common on PCs and other full-size keyboards (although direct input is also widely supported), whereas direct kana input is typically used on mobile phones and similar devices – each of the 10 digits (1–9,0) corresponds to one of the 10 columns in the gojūon table of kana, and multiple presses select the row.
There are two main systems for the romanization of Japanese, known as Kunrei-shiki and Hepburn; in practice, "keyboard romaji" (also known as wāpuro rōmaji or "word processor romaji") generally allows a loose combination of both. IME implementations may even handle keys for letters unused in any romanization scheme, such as L, converting them to the most appropriate equivalent. With kana input, each key on the keyboard directly corresponds to one kana. The JIS keyboard system is the national standard, but there are alternatives, like the thumb-shift keyboard, commonly used among professional typists.

Famous quotes containing the words text and/or input:
“The power of a text is different when it is read from when it is copied out.... Only the copied text thus commands the soul of him who is occupied with it, whereas the mere reader never discovers the new aspects of his inner self that are opened by the text, that road cut through the interior jungle forever closing behind it: because the reader follows the movement of his mind in the free flight of day-dreaming, whereas the copier submits it to command.”
—Walter Benjamin (1892–1940)
“Celebrity is a mask that eats into the face. As soon as one is aware of being “somebody,” to be watched and listened to with extra interest, input ceases, and the performer goes blind and deaf in his overanimation. One can either see or be seen.”
—John Updike (b. 1932)
