The German keyboard layout is a QWERTZ keyboard layout commonly used in Austria and Germany. It is based on one defined in a former edition (October 1988) of the German standard DIN 2137-2. The current edition DIN 2137-1:2012-06 standardizes it as the first (basic) one of three layouts, calling it “T1” (“Tastaturbelegung 1” = “keyboard layout 1”). The German layout differs from the English (US and UK) layouts in four major ways: * The positions of the "Z" and "Y" keys are switched, this change being made for two major reasons: : * "Z" is a much more common letter than "Y" in German; the latter rarely appears outside words whose spellings reflect either their importation from a foreign language or the Hellenization of an older German form under the influence of Ludwig I of Bavaria. : * "T" and "Z" often appear next to each other in the German orthography, and placing the two keys next to each other minimizes the effort needed for typing the two characters in sequence (''cf.'' the use of a single-block ''tz'' ligature in many early mechanical printing presses using ''fraktur'' typefaces). * Part of the keyboard is adapted to include umlauted vowels (''ä'', ''ö'', ''ü''). * The placements of some special symbols are changed, some of special key inscriptions are changed from an abbreviation to a graphical symbol (for example "Caps Lock" becomes a hollow arrow pointing down, "Backspace" becomes a left-pointing arrow), and most of the other abbreviations are replaced by German abbreviations (thus e.g. "Ctrl" for "control" is translated to its German equivalent "Strg" for "Steuerung"). "Esc" for "escape" is not translated however. * Like many other non-American keyboards, German keyboards change the right Alt key into an Alt Gr key to access a third level of key assignments. This is necessary because the umlauts and some other special characters leave no room to have all the special symbols of ASCII, needed by programmers among others, available on the first or second (shifted) levels without unduly increasing the size of the keyboard. ==General information== File:German-Keyboard-Layout-T2-Version2-large.png|thumb|upright=2.5|German keyboard layout “T2” according to DIN 2137-1:2012-06.

µ, and ~ are accessed by holding the key and tapping the other key. The key on the left will not access these additional characters. Alternatively and pressing the respective key also produce the alternative characters on some operating systems. The accent keys , , are dead keys: press and release an accent key, then press a letter key to produce accented characters (ô, á, ù, etc.; the current DIN 2137-1:2012-06 extends this for e.g. ń, ś etc.). If the entered combination is not encoded in Unicode by a single code point (precomposed character), most current implementations cause the display of a free-standing (spacing) version of the accent followed by the unaccented base letter. This behavior (which is explicitly not compliant with the current DIN 2137-1:2012-06) leads some users suffering from insufficient typing skills to mistype a spacing accent instead of an apostrophe (e.g., ''it´s'' or ''it`s'' instead of correctly ''it’s'').〔Markus Kuhn: (Apostrophe and acute accent confusion ), 2001.〕 Note that the semicolon and colon are accessed by using the key. The “T1” layout lacks some important characters like the German style quotation marks („ and “ and ‚ ‘ respectively). As a consequence, these are seldom used in Internet communication, " and ' are used instead. The “T2” layout newly defined in DIN 2137-1:2012-06 was designed to overcome such restrictions, but in first line to enable the writing of all primary languages of all countries of the world, as long as these use the Latin script. Therefore, it contains several additional diacritical marks and punctuation characters, including the full set of German, English, and French style quotation marks in addition to the typographic apostrophe, the prime, the double prime, and the ʻokina. The image shows characters to be entered using in the lower left corner of each key depiction (characters not contained in the “T1” layout are marked red). Diacritical marks are marked by a flat rectangle which also indicates the position of the diacritical mark relative to the base letter. The characters in shown at the right border of a keytop are accessed by pressing a special key combination before; for those marked green the corresponding capital letter is available by pressing the Shift key simultaneously. In addition, DIN 2137-1:2012-06 defines a layout “T3”, which is a superset of “T2” incorporating the whole “secondary group” as defined in ISO/IEC 9995-3:2010. Thus, it enables to write several minority languages (e.g. Sami) and transliterations, but is more difficult to comprehend than the “T2” layout, and therefore not expected to be accepted by a broad audience beyond experts who need this functionality. Contrary to many other languages, German keyboards are usually not labeled in English (in fact, DIN 2137-1:2012-06 requires either the symbol according to ISO/IEC 9995-7 or the German abbreviation is to be used, with “ESC” as an exception). The abbreviations used on German keyboards are: On some keyboards, the asterisk ( *) key on the numeric keypad is instead labeled with the multiplication sign (×) and the divide-key is labeled with the division sign (÷) instead of slash (/). The behaviour of according to former editions of the DIN 2137 standard is inherited from mechanical typewriters: Pressing it once shifts all keys including numbers and special characters until the key is pressed again. Holding while is active unshifts all keys. Both and lack any textual labels. The key is simply labeled with a large down-arrow (on newer designs pointing to an uppercase A letter) and is labeled with a large up-arrow. The current DIN 2137-1:2012-06 simply requests the presence of a “capitals lock” key (which is the name used in the ISO/IEC 9995 series), without any description of its function. In IT, an alternative behaviour is often preferred, usually described as "IBM", which is the same as on English keyboards – only letters are shifted, and hitting again releases it. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「German keyboard layout」の詳細全文を読む スポンサード リンク
