and sold to E. Remington and Sons in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in ubiquitous use.


History

The QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a

editor and printer who lived in Kenosha, Wisconsin. In October 1867, Sholes filed a patent application for his early writing machine he developed with the assistance of his friends Carlos Glidden and Samuel W. Soulé. The first model constructed by Sholes used a piano-like keyboard with two rows of characters arranged alphabetically as shown below:
- 3 5 7 9 N O P Q R S T U V W X Y Z
2 4 6 8 . A B C D E F G H I J K L M
Sholes struggled for the next five years to perfect his invention, making many trial-and-error rearrangements of the original machine's alphabetical key arrangement. The study of bigram (letter-pair) frequency by educator Amos Densmore, brother of the financial backer James Densmore, is believed to have influenced the array of letters, but the contribution was later called into question. Others suggest instead that the letter groupings evolved from telegraph operators' feedback. In November 1868 he changed the arrangement of the latter half of the alphabet, O to Z, right-to-left. In April 1870 he arrived at a four-row, upper case keyboard approaching the modern QWERTY standard, moving six vowel letters, A, E, I, O, U, and Y, to the upper row as follows:
2 3 4 5 6 7 8 9 -
A E I . ? Y U O ,
B C D F G H J K L M
Z X W V T S R Q P N
In 1873 Sholes's backer, James Densmore, successfully sold the manufacturing rights for the Sholes & Glidden Type-Writer to E. Remington and Sons. The keyboard layout was finalized within a few months by Remington's mechanics and was ultimately presented:
2 3 4 5 6 7 8 9 - ,
Q W E . T Y I U O P
Z S D F G H J K L M
A X & C V B N ? ; R
After they purchased the device, Remington made several adjustments, creating a keyboard with essentially the modern QWERTY layout. These adjustments included placing the "R" key in the place previously allotted to the period key. Apocryphal claims that this change was made to let salesmen impress customers by pecking out the brand name "TYPE WRITER QUOTE" from one keyboard row are not formally substantiated. Vestiges of the original alphabetical layout remained in the "

The QWERTY layout became popular with the success of the Remington No. 2 of 1878, the first typewriter to include both upper and lower case letters, using a shift key. One popular but unverified explanation for the QWERTY arrangement is that it was designed to reduce the likelihood of internal clashing of typebars by placing commonly used combinations of letters farther from each other inside the machine.David, P. A. (1986). "Understanding the Economics of QWERTY: the Necessity of History". In Parker, William N., ''Economic History and the Modern Economist''. Basil Blackwell, New York and Oxford.


Differences from modern layout


Substituting characters

The QWERTY layout depicted in Sholes's 1878 patent is slightly different from the modern layout, most notably in the absence of the numerals 0 and 1, with each of the remaining numerals shifted one position to the left of their modern counterparts. The letter M is located at the end of the third row to the right of the letter L rather than on the fourth row to the right of the N, the letters X and C are reversed, and most
punctuation marks Punctuation (or sometimes interpunction) is the use of spacing, conventional signs (called punctuation marks), and certain typographical devices as aids to the understanding and correct reading of written text, whether read silently or aloud. An ...
are in different positions or are missing entirely. 0 and 1 were omitted to simplify the design and reduce the manufacturing and maintenance costs; they were chosen specifically because they were "redundant" and could be recreated using other keys. Typists who learned on these machines learned the habit of using the uppercase letter I (or lowercase letter L) for the digit one, and the uppercase O for the zero. The 0 key was added and standardized in its modern position early in the history of the typewriter, but the 1 and exclamation point were left off some typewriter keyboards into the 1970s.


Combined characters

In early designs, some characters were produced by printing two symbols with the carriage in the same position. For instance, the exclamation point, which shares a key with the numeral 1 on post-mechanical keyboards, could be reproduced by using a three-stroke combination of an apostrophe, a backspace, and a period. A semicolon (;) was produced by printing a comma (,) over a colon (:). As the backspace key is slow in simple mechanical typewriters (the carriage was heavy and optimized to move in the opposite direction), a more professional approach was to block the carriage by pressing and holding the space bar while printing all characters that needed to be in a shared position. To make this possible, the carriage was designed to advance forward only after releasing the space bar. In the era of mechanical typewriters, combined characters such as ''é'' and ''õ'' were created by the use of dead keys for the diacritics (''′, ~''), which did not move the paper forward. Thus the ''′'' and ''e'' would be printed at the same location on the paper, creating ''é''.


Contemporary alternatives

There were no particular technological requirements for the QWERTY layout, since at the time there were ways to make a typewriter without the "up-stroke" typebar mechanism that had required it to be devised. Not only were there rival machines with "down-stroke" and "frontstroke" positions that gave a visible printing point, the problem of typebar clashes could be circumvented completely: examples include Thomas Edison's 1872 electric print-wheel device which later became the basis for Teletype machines;
Lucien Stephen Crandall Lucien Stephen Crandall (May 4, 1844 – February 4, 1919) was an American inventor of typewriters, adding machines and electrical devices. Crandall gave his name to several typewriters, and he was also involved in the development of various mac ...

Properties

Alternating hands while typing is a desirable trait in a keyboard design. While one hand types a letter, the other hand can prepare to type the next letter, making the process faster and more efficient. In the QWERTY layout many more words can be spelled using only the left hand than the right hand. In fact, thousands of English words can be spelled using only the left hand, while only a couple of hundred words can be typed using only the right hand (the three most frequent letters in the English language, ETA, are all typed with the left hand). In addition, more typing strokes are done with the left hand in the QWERTY layout. This is helpful for left- handed people but disadvantageous for right-handed people. Contrary to popular belief, the QWERTY layout was not designed to slow the typist down, but rather to speed up typing. Indeed, there is evidence that, aside from the issue of jamming, placing often-used keys farther apart increases typing speed, because it encourages alternation between the hands. (On the other hand, in the German keyboard the Z has been moved between the T and the U to help type the frequent digraphs TZ and ZU in that language.) Almost every word in the English language contains at least one vowel letter, but on the QWERTY keyboard only the vowel letter "A" is on the home row, which requires the typist's fingers to leave the home row for most words. A feature much less commented-on than the order of the keys is that the keys do not form a rectangular grid, but rather each column slants diagonally. This is because of the mechanical linkages – each key is attached to a lever, and hence the offset prevents the levers from running into each other – and has been retained in most electronic keyboards. Some keyboards, such as the Kinesis or TypeMatrix, retain the QWERTY layout but arrange the keys in vertical columns, to reduce unnecessary lateral finger motion.


Computer keyboards

The first computer terminals such as the Teletype were typewriters that could produce and be controlled by various computer codes. These used the QWERTY layouts and added keys such as

(ESC) which had special meanings to computers. Later keyboards added function keys and arrow keys. Since the standardization of PC-compatible computers and Windows after the 1980s, most full-sized computer keyboards have followed this standard (see drawing at right). This layout has a separate numeric keypad for data entry at the right, 12 function keys across the top, and a cursor section to the right and center with keys for

Other keys and characters


Specific language variants

Minor changes to the arrangement are made for other languages. There are a large number of different keyboard layouts used for different languages written in Latin script. They can be divided into three main families according to where the , , , , and keys are placed on the keyboard. These are usually named after the first six letters, for example this QWERTY layout and the AZERTY layout. In this section you will also find keyboard layouts that include some additional symbols of other languages. But they are different from layouts that were designed with the goal to be usable for multiple languages (see Multilingual variants). The following sections give general descriptions of QWERTY keyboard variants along with details specific to certain operating systems. The emphasis is on Microsoft Windows.

Sometimes it is placed one line below its traditional situation, on the right of the apostrophe key (') (in these cases the enter key is narrower than usual on the line of its default location). It may also be two lines below its default situation on the right of a narrower than traditionally right shift key. A variant of this layout is used in Arabic-speaking countries. This variant has the , \ key to the left of Z, ~ ` key where the , \ key is in the usual layout, and the > < key where the ~ ` key is in the usual layout.


Czech

The typewriter came to the Czech-speaking area in the late 19th century, when it was part of Austria-Hungary where German was the dominant language of administration. Therefore, Czech typewriters have the QWERTZ layout. However, with the introduction of imported computers, especially since the 1990s, the QWERTY keyboard layout is frequently used for computer keyboards. The Czech QWERTY layout differs from QWERTZ in that the characters (e.g. @$& and others) missing from the Czech keyboard are accessible with AltGr on the same keys where they are located on an American keyboard. In Czech QWERTZ keyboards the positions of these characters accessed through AltGr differs.


Danish

Both the Danish and Norwegian keyboards include dedicated keys for the letters Å/å, Æ/æ and Ø/ø, but the placement is a little different, as the and keys are swapped on the Norwegian layout. (The Finnish–Swedish keyboard is also largely similar to the Norwegian layout, but the and are replaced with and . On some systems, the Danish keyboard may allow typing Ö/ö and Ä/ä by holding the or key while striking and , respectively.) Computers with Windows are commonly sold with ÖØÆ and ÄÆØ printed on the two keys, allowing same computer hardware to be sold in Denmark, Finland, Norway and Sweden, with different operating system settings.


Dutch (Netherlands)

Though it is seldom used (most Dutch keyboards use US International layout), the Dutch layout uses QWERTY but has additions for the € sign, the diaresis (¨), and the braces () as well as different locations for other symbols. An older version contained a single-stroke key for the Dutch character IJ/ij, which is usually typed by the combination of and . In the 1990s, there was a version with the now-obsolete

French (Canada)

This keyboard layout is commonly used in Canada by French-speaking Canadians. It is the most common layout for laptops and stand-alone keyboards aimed at the Francophone market. Unlike the AZERTY layout used in France and Belgium, it is a QWERTY layout and as such is also relatively commonly used by English speakers in the US and Canada (accustomed to using US standard QWERTY keyboards) for easy access to the accented letters found in some French loanwords. It can be used to type all accented French characters, as well as some from other languages, and serves all English functions as well. It is popular mainly because of its close similarity to the basic US keyboard commonly used by English-speaking Canadians and Americans and historical use of US-made typewriters by French-Canadians. It can also easily 'map' to or from a standard US QWERTY keyboard with the sole loss the guillemet/ degree sign key. Its significant difference from the US standard is that the right Alt key is reconfigured as an

key that gives easy access to a further range of characters (marked in blue and red on the keyboard image. Blue indicates an alternative character that will display as typed. Red indicates a dead key: the diacritic will be applied to the next vowel typed.) In some variants, the key names are translated to French: * is or (short for ''Fixer''/''Verrouiller Majuscule'', meaning ''Lock Uppercase''). * is . * is .


Greek

* The stress accents, indicated in red, are produced by pressing that key (or shifted key) followed by an appropriate vowel. * Use of the "AltGr" key may produce the characters shown in blue.


German

Germany, Austria, Switzerland, Liechtenstein, and Luxembourg use QWERTZ layouts, where the letter Z is to the right of T.


Icelandic

The Icelandic keyboard layout is different from the standard QWERTY keyboard because the Icelandic alphabet has some special letters, most of which it shares with the other Nordic countries: Þ/þ, Ð/ð, Æ/æ, and Ö/ö. (Æ/æ also occurs in Norwegian, Danish and Faroese, Ð/ð in Faroese, and Ö/ö in Swedish, Finnish and Estonian. In Norwegian Ö/ö could be substituted for Ø/Ø which is the same sound/letter and is widely understood). The letters Á/á, Ý/ý, Ú/ú, Í/í, and É/é are produced by first pressing the dead key and then the corresponding letter. The Nordic letters Å/å and Ä/ä can be produced by first pressing , located below the key, and (for ¨) which also works for the non-Nordic ÿ, Ü/ü, Ï/ï, and Ë/ë. These letters are not used natively in Icelandic, but may have been implemented for ease of communication in other Nordic languages. Additional diacritics may be found behind the key: for ˋ (grave accent) and for ˆ (circumflex).


Irish

Microsoft Windows includes an Irish layout which supports acute accents with for the
Irish language Irish (Standard Irish: ), also known as Gaelic, is a Goidelic language of the Insular Celtic branch of the Celtic language family, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was ...
and grave accents with the dead key for Scots Gaelic. The other Insular Celtic languages have their own layout. The UK or UK-Extended layout is also frequently used.


Italian

* Braces (right above square brackets and shown in purple) are given with both AltGr and Shift pressed. * The tilde (~) and backquote (`) characters are not present on the Italian keyboard layout (with Linux, they are available by pressing ++, and ++; Windows might not recognise these keybindings). * When using Microsoft Windows, the standard Italian keyboard layout does not allow one to write 100% correct Italian language, since it lacks capital accented vowels, and in particular the È key. The common workaround is writing E' (E followed by an apostrophe) instead, or relying on the auto-correction feature of several word processors when available. It is possible to obtain the È symbol in MS Windows by typing + . Mac users, however, can write the correct accented character by pressing + + or, in the usual Mac way, by pressing the correct key for the accent (in this case + ) and subsequently pressing the wanted letter (in this case + ). Linux users can also write it by pressing the key with enabled. There is an alternate layout, which differs only in disposition of characters accessible through , and includes the tilde and the curly brackets. It is commonly used in IBM keyboards. Italian typewriters often have the QZERTY layout instead. The Italian-speaking part of

Latvian

Although rarely used, a keyboard layout specifically designed for the Latvian language called ŪGJRMV exists. The Latvian QWERTY keyboard layout is most commonly used; its layout is the same as Latin ones, but with a dead key, which allows entering special characters (āčēģīķļņõŗšūž). The most common dead key is the apostrophe ('), which is followed by Alt+Gr (Windows default for Latvian layout). Some prefer using the tick (`).


Lithuanian

Where in standard QWERTY the number row is located, you find in Lithuanian QWERTY: Ą, Č, Ę, Ė, Į, Š, Ų, Ū, Ž, instead of their counterparts 1, 2, 3, 4, 5, 6, 7, 8, =. If you still want to use the numbers of the mentioned 'number row', you can create them in combination with the -key. Aside from these changes the keyboard is standard QWERTY. Besides QWERTY, the ĄŽERTY layout without the adjustment of the number row is used.


Maltese

The Maltese language uses Unicode (UTF-8) to display the Maltese diacritics: ċ Ċ; ġ Ġ; ħ Ħ; ż Ż (together with à À; è È; ì Ì; ò Ò; ù Ù). There ar
two standard keyboard layouts for Maltese
according to "MSA 100:2002 Maltese Keyboard Standard"; one of 47 keys and one of 48 keys. The 48-key layout is the most popular.


Norwegian

The Norwegian languages use the same letters as Danish, but the Norwegian keyboard differs from the Danish layout regarding the placement of the , and ( backslash) keys. On the Danish keyboard, the and are swapped. The Swedish keyboard is also similar to the Norwegian layout, but and are replaced with and . On some systems, the Norwegian keyboard may allow typing Ö/ö and Ä/ä by holding the or key while striking and , respectively. There is also an alternative keyboard layout called ''Norwegian with Sámi'', which allows for easier input of the characters required to write various Sámi languages. All the Sámi characters are accessed through the key. On Macintosh computers, the ''Norwegian'' and ''Norwegian extended'' keyboard layouts have a slightly different placement for some of the symbols obtained with the help of the or keys. Notably, the ''$'' sign is accessed with and ''¢'' with . Furthermore, the frequently used ''@'' is placed between and .


Polish

Most typewriters use a QWERTZ keyboard with Polish letters (with diacritical marks) accessed directly (officially approved as "Typist's keyboard", pl , klawiatura maszynistki, Polish Standard PN-87), which is mainly ignored in Poland as impractical (custom-made keyboards, e.g., those in the public sector as well as some Apple computers, present an exception to this paradigm); the "Polish programmer's" ( pl, polski programisty) layout has become the ''de facto'' standard, used on virtually all computers sold on the Polish market. Most computer keyboards in Poland are laid out according to the standard US visual and functional layout. Polish diacritics are accessed by using the ''

'' key with a corresponding similar letter from the base Latin alphabet. Normal capitalization rules apply with respect to '' Shift'' and '' Caps Lock'' keys. For example, to enter "Ź", one can type ''Shift+AltGr+X'' with ''Caps Lock'' off, or turn on ''Caps Lock'' and type ''AltGr+X''. Both ANSI and ISO mechanical layouts are common sights, and even some non-standard mechanical layouts are in use. ANSI is often preferred, as the additional key provides no additional function, at least in Microsoft Windows where it duplicates the backslash key, while taking space from the Shift key. Many keyboards do not label ''AltGr'' as such, leaving the ''Alt'' marking as in the US layout - the right ''Alt'' key nevertheless functions as ''AltGr'' in this layout, causing possible confusion when keyboard shortcuts with the ''Alt'' key are required (these usually work only with the left ''Alt'') and causing the key to be commonly referred to as ''right Alt'' ( pl, prawy Alt). However, keyboards with ''AltGr'' marking are available and it is also officially used by Microsoft when depicting the layout. Also, on MS Windows, the tilde character "~" (''Shift''+''`'') acts as a dead key to type Polish letters (with diacritical marks) thus, to obtain an "Ł", one may press ''Shift''+''`'' followed by ''L''. The tilde character is obtained with (''Shift''+''`'') then ''space''. In

Portuguese


Brazil

The Brazilian computer keyboard layout is specified in the ABNT NBR 10346 variant 2 (alphanumeric portion) and 10347 (numeric portion) standards. Essentially, the Brazilian keyboard contains dead keys for five variants of diacritics in use in the language; the letter Ç, the only application of the cedilla in Portuguese, has its own key. In some keyboard layouts the + combination produces the ₢ character ( Unicode 0x20A2), symbol for the old currency cruzeiro, a symbol that is not used in practice (the common abbreviation in the eighties and nineties used to be Cr$). The cent sign ¢, is accessible via +, but is not commonly used for the centavo, subunit of previous currencies as well as the current real, which itself is represented by R$. The Euro sign € is not standardized in this layout. The masculine and feminine ordinals ª and º are accessible via combinations. The

Variant 2 of the Brazilian keyboard, the only which gained general acceptance (MS Windows treats both variants as the same layout), has a unique mechanical layout, combining some features of the

Its modern, IBM PS/2-based variations, are thus known as 107-keys keyboards, and the original PS/2 variation was 104-key. Variant 1, never widely adopted, was based on the ISO 9995-2 keyboards. To make this layout usable with keyboards with only 11 keys in the last row, the rightmost key (/?°) has its functions replicated across the +, +, and + combinations.


Portugal

Essentially, the Portuguese keyboard contains dead keys for five variants of diacritics; the letter Ç, the only application of the cedilla in Portuguese, has its own key, but there are also a dedicated key for the ordinal indicators and a dedicated key for quotation marks. The + combination for producing the euro sign € ( Unicode 0x20AC) has become standard. On some QWERTY keyboards the key labels are translated, but the majority are labelled in English. During the 20th century, a different keyboard layout,

Romanian (in Romania and Moldova)

The current Romanian National Standard SR 13392:2004 establishes two layouts for

keyboards: a "primary" one and a "secondary" one. The "primary" layout is intended for traditional users who have learned how to type with older, Microsoft-style implementations of the Romanian keyboard. The "secondary" layout is mainly used by programmers as it does not contradict the physical arrangement of keys on a US-style keyboard. The "secondary" arrangement is used as the default Romanian layout by

distributions, as defined in the "X Keyboard Configuration Database". There are four Romanian-specific characters that are incorrectly implemented in versions of Microsoft Windows until Vista came out: * Ș (U+0218, S with comma), incorrectly implemented as Ş (U+015E, S with cedilla) * ș (U+0219, s with comma), incorrectly implemented as ş (U+015F, s with cedilla) * Ț (U+021A, T with comma), incorrectly implemented as Ţ (U+0162, T with cedilla) * ț (U+021B, t with comma), incorrectly implemented as ţ (U+0163, t with cedilla) The cedilla-versions of the characters do not exist in the Romanian language (they came to be used due to a historic bug). The UCS now says that encoding this was a mistake because it messed up Romanian data and the letters with cedilla and the letters with comma are the same letter with a different style. Since Romanian hardware keyboards are not widely available, Cristian Secară has created a driver that allows Romanian characters to be generated with a US-style keyboard in all versions of Windows prior to Vista through the use of the AltGr key modifier. Windows Vista and newer versions include the correct diacritical signs in the default Romanian Keyboard layout. This layout has the Z and Y keys mapped like in English layouts and also includes characters like the 'at' (@) and dollar ($) signs, among others. The older cedilla-version layout is still included albeit as the 'Legacy' layout.


Slovak

In Slovakia, similarly to the Czech Republic, both QWERTZ and QWERTY keyboard layouts are used. QWERTZ is the default keyboard layout for Slovak in Microsoft Windows.


Spanish


Spain

The Spanish keyboard layout is used to write in Spanish and in other languages of Spain such as
Catalan Catalan may refer to: Catalonia From, or related to Catalonia: * Catalan language, a Romance language * Catalans, an ethnic group formed by the people from, or with origins in, Northern or southern Catalonia Places * 13178 Catalan, asteroid #1 ...
, Basque, Galician, Aragonese, Asturian and Occitan. It includes Ñ for Spanish, Asturian and Galician, the acute accent, the diaeresis, the inverted question and exclamation marks (¿, ¡), the superscripted o and a (º, ª) for writing abbreviated ordinal numbers in masculine and feminine in Spanish and Galician, and finally, some characters required only for typing Catalan and Occitan, namely Ç, the grave accent and the interpunct (' / ', used in ''l·l, n·h, s·h''; located at Shift-3). It can also be used to write other international characters, such as those using a circumflex accent (used in French and Portuguese among others) or a tilde (used in both Spanish and Portuguese), which are available as

. However, it lacks two characters used in Asturian: and (historically, general support for these two has been poor – they aren't present in the ISO 8859-1 character encoding standard, or any other ISO/IEC 8859 standard). Several alternative distributions, based on this one or created from scratch, have been created to address this issue (see the Other original layouts and layout design software section for more information). On most keyboards, € is marked as Alt Gr + E and not Alt Gr + 5 as shown in the image. However, in some keyboards, € is found marked twice. An alternative version exists, supporting all of ISO 8859-1. Spanish keyboards are usually labelled in Spanish instead of English, its abbreviations being: On some keyboards, the c-cedilla key (Ç) is located one or two lines above, rather than on the right of, the acute accent key (´). In some cases it is placed on the right of the plus sign key (+), while in other keyboards it is situated on the right of the inverted exclamation mark key (¡).

and South America. Before its design, Latin American vendors had been selling the Spanish (Spain) layout as default. Its most obvious difference from the Spanish (Spain) layout is the lack of a Ç key; on Microsoft Windows it lacks a tilde (~) dead key, whereas on Linux systems the dead tilde can be optionally enabled. This is not a problem when typing in Spanish, but it is rather problematic when typing in Portuguese, which can be an issue in countries with large commercial ties to Brazil (

, as the letters Ä/ä and Ö/ö are shared with the Swedish language, and even Å/å is needed by Swedish-speaking Finns. However, the Finnish multilingual keyboard adds new letters and punctuation to the functional layout. The Norwegian keyboard largely resembles the Swedish layout, but the and are replaced with and . The Danish keyboard is also similar, but it has the and swapped. On some systems, the Swedish or Finnish keyboard may allow typing Ø/ø and Æ/æ by holding the or key while striking and , respectively. The ''Swedish with Sámi'' keyboard allows typing not only Ø/ø and Æ/æ, but even the letters required to write various Sámi languages. This keyboard has the same function for all the keys engraved on the regular Swedish keyboard, and the additional letters are available through the key. On Macintosh computers, the ''Swedish'' and ''Swedish Pro'' keyboards differ somewhat from the image shown above, especially as regards the characters available using the or keys.

Turkish

Today the majority of Turkish keyboards are based on QWERTY (the so-called Q-keyboard layout), although there is also the older F-keyboard layout specifically designed for the language.


Vietnamese

The Vietnamese keyboard layout is an extended Latin QWERTY layout. The letters Ă, Â, Ê, and Ô are found on what would be the number keys – on the US English keyboard, with – producing the tonal marks ( grave accent, hook, tilde, acute accent and dot below, in that order), producing Đ, producing the đồng sign (₫) when not shifted, and brackets () producing Ư and Ơ.


Multilingual variants

Multilingual keyboard layouts, unlike the default layouts supplied for one language and market, try to make it possible for the user to type in any of several languages using the same number of keys. Mostly this is done by adding a further virtual layer in addition to the -key by means of (or 'right ' reused as such), which contains a further repertoire of symbols and diacritics used by the desired languages. This section also tries to arrange the layouts in ascending order by the number of possible languages and not chronologically according to the Latin alphabet as usual.


United Kingdom (Extended) Layout


Windows

From
Windows XP SP2 Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and ...
onwards, Microsoft has included a variant of the British QWERTY keyboard (the "United Kingdom Extended" keyboard layout) that can additionally generate several diacritical marks. This supports input on a standard physical UK keyboard for many languages without changing positions of frequently used keys, which is useful when working with text in

, Scots Gaelic and Irish — languages native to parts of the UK ( Wales, parts of Scotland and Northern Ireland respectively). In this layout, the grave accent key () becomes, as it also does in the US International layout, a dead key modifying the character generated by the next key pressed. The apostrophe, double-quote, tilde and circumflex ( caret) keys are not changed, becoming dead keys only when 'shifted' with . Additional precomposed characters are also obtained by shifting the 'normal' key using the key. The extended keyboard is software installed from the Windows control panel, and the extended characters are not normally engraved on keyboards. The UK Extended keyboard uses mostly the AltGr key to add diacritics to the letters a, e, i, n, o, u, w and y (the last two being used in Welsh) as appropriate for each character, as well as to their capitals. Pressing the key and then a character that does not take the specific diacritic produces the behaviour of a standard keyboard. The key presses followed by spacebar generate a stand-alone mark.: * grave accents (e.g. à, è, etc.) needed for Scots Gaelic are generated by pressing the grave accent (or 'backtick') key , which is a dead key, then the letter. Thus produces à. * acute accents (e.g. á) needed for Irish are generated by pressing the key together with the letter (or acting as a dead key combination followed by the letter). Thus produces á; produces Á. (Some programs use the combination of and a letter for other functions, in which case the method must be used to generate acute accents). * the circumflex diacritic needed for Welsh may be added by , acting as a dead key combination, followed by the letter. Thus then produces â, then produces the letter ŵ. Some other languages commonly studied in the UK and Ireland are also supported to some extent: * diaeresis or umlaut (e.g. ä, ë, ö, etc.) is generated by a dead key combination , then the letter. Thus produces ä. * tilde (e.g. ã, ñ, õ, etc., as used in Spanish and Portuguese) is generated by dead key combination , then the letter. Thus produces ã. * cedilla (e.g. ç) under c is generated by , and the capital letter (Ç) is produced by The and letter method used for acutes and cedillas does not work for applications which assign shortcut menu functions to these key combinations. These combinations are intended to be mnemonic and designed to be easy to remember: the circumflex accent (e.g. â) is similar to the free-standing circumflex (caret) (^), printed above the key; the diaeresis/umlaut (e.g. ö) is visually similar to the double-quote (") above on the UK keyboard; the tilde (~) is printed on the same key as the . The UK Extended layout is almost entirely transparent to users familiar with the UK layout. A machine with the extended layout behaves exactly as with the standard UK, except for the rarely used grave accent key. This makes this layout suitable for a machine for shared or public use by a user population in which some use the extended functions. Despite being created for multilingual users, UK-Extended in Windows does have some gaps — there are many languages that it cannot cope with, including Romanian and Turkish, and all languages with different character sets, such as Greek and Russian. It also does not cater for

ChromeOS

The UK Extended layout (a ChromeOS extension) provides all the same combinations as with Windows, but adds many more symbols and dead keys via AltGr. Notes: Dotted circle (◌) is used here to indicate a dead key. The key is the only one that acts as a free-standing dead key and thus does not respond as shown on the key-cap. All others are invoked by AltGr.

US-International


Windows and Linux

An alternative layout uses the physical US keyboard to type diacritics in some operating systems (including Windows). This is the US-International layout setting, which uses the right key as an key to support many additional characters directly as an additional shift key. (Since many smaller keyboards don't have a right- key, Windows also allows + to be used as a substitute for .) This layout also uses keys , , , and as dead keys to generate characters with diacritics by pressing the appropriate key, then the letter on the keyboard. The international keyboard is a software setting installed from the Windows control panel or similar; the additional functions (shown in blue) may or may not be engraved on the keyboard, but are always functional. It can be used to type most major languages from Western Europe: Afrikaans, Danish, Dutch,

, Maltese, Czech and Hungarian), are not fully supported by the US-International keyboard layout because of their use of additional diacritics or precomposed characters. A diacritic key is activated by pressing and releasing it, then pressing the letter that requires the diacritic. After the two strokes, the single character with diacritics is generated. Note that only certain letters, such as vowels and "n", can have diacritics in this way. To generate the symbols ', `, ", ^ and ~, when the following character is capable of having a diacritic, press the after the key. Characters with diacritics can be typed with the following combinations: * + vowel → vowel with acute accent, e.g., → é * + vowel → vowel with grave accent, e.g., → è * + vowel → vowel with diaeresis (or umlaut), e.g., → ë * + vowel → vowel with circumflex accent, e.g., → ê * + , or → letter with tilde, e.g. → ñ, → õ * + → ç (Windows) or ć (X11) The US-International layout is not entirely transparent to users familiar with the conventional US layout; when using a machine with the international layout setting active, the commonly used single- and double-quote keys and the less commonly used grave accent, tilde, and circumflex (caret) keys are dead keys and thus behave unconventionally. This could be disconcerting on a machine for shared or public use. There are also alternative US-International mappings, whereby modifier keys such as shift and alt are used, and the keys for the characters with diacritics are in different places from their unmodified counterparts. For example, the right-Alt key may be remapped as an AltGr modifier key or as a compose key and the dead key function deactivated, so that they (the ASCII quotation marks and circumflex symbol) can be typed normally with a single keystroke.

This is practical, as Finnish and Swedish share the special characters Ä/ä and Ö/ö, and while the Swedish Å/å is unnecessary for writing Finnish, it is needed by Swedish-speaking Finns and to write Swedish family names which are common. As of 2008, there is a new standard for the Finnish multilingual keyboard layout, developed as part of a localization project by CSC. All the engravings of the traditional Finnish–Swedish visual layout have been retained, so there is no need to change the hardware, but the functionality has been extended considerably, as additional characters (e.g., Æ/æ, Ə/ə, Ʒ/ʒ) are available through the key, as well as dead keys, which allow typing a wide variety of letters with diacritics (e.g., Ç/ç, Ǥ/ǥ, Ǯ/ǯ).

letters Ș/ș and Ț/ț (S/s and T/t with comma below) are not supported; the presumption is that Ş/ş and Ţ/ţ (with cedilla) suffice as surrogates.


EurKEY

EurKEY, a multilingual keyboard layout intended for Europeans, programmers and translators which uses the US-standard QWERTY layout as base and adds a third and fourth layer available through the key and +. These additional layers provide support for many Western European languages, special characters, the Greek alphabet (via dead keys), and many common mathematical symbols. Unlike most of the other QWERTY layouts, which are formal standards for a country or region, EurKEY is not an EU, EFTA or any national standard. To address the ergonomics issue of QWERTY, EurKEY Colemak-DH was also developed a Colmak-DH version with the EurKEY design principles.


Alternatives

Several alternatives to QWERTY have been developed over the years, claimed by their designers and users to be more efficient, intuitive, and ergonomic. Nevertheless, none have seen widespread adoption, partly due to the sheer dominance of available keyboards and training. Although some studies have suggested that some of these may allow for faster typing speeds,Paul David, "Understanding the economics of QWERTY: the necessity of history", '' Economic history and the modern economist'', 1986 many other studies have failed to do so, and many of the studies claiming improved typing speeds were severely methodologically flawed or deliberately biased, such as the studies administered by
August Dvorak August Dvorak (May 5, 1894 – October 10, 1975) was an American educational psychologist and professor of education at the University of Washington in Seattle, Washington. He and his brother-in-law, William Dealey, are best known fo ...

. Economists Stan Liebowitz and Stephen Margolis have noted that rigorous studies are inconclusive as to whether they actually offer any real benefits, and some studies on keyboard layout have suggested that, for a skilled typist, layout is largely irrelevanteven randomized and alphabetical keyboards allow for similar typing speeds to QWERTY and Dvorak keyboardsand that switching costs always outweigh the benefits of further training with a keyboard layout a person has already learned. The most widely used such alternative is the

; another alternative is Colemak, which is based partly on QWERTY and is claimed to be easier for an existing QWERTY typist to learn while offering several supposed optimisations. Most modern computer operating systems support these and other alternative mappings with appropriate special mode settings, with some modern operating systems allowing the user to map their keyboard in any way they like, but few keyboards are made with keys labeled according to any other standard.


Comparison to other keyboard input systems

Comparisons have been made between Dvorak, Colemak, QWERTY, and other keyboard input systems, namely stenotype or its electronic implementations. However, stenotype is a fundamentally different system, which relies on phonetics and simultaneous key presses or chords. Although Shorthand (or 'stenography') has long been known as a faster and more accurate typing system, adoption has been limited, possibly due to the historically high cost of equipment, steeper initial learning curve, and low awareness of the benefits within primary education and in the general public. The first typed shorthand machines appeared around 1830, with English versions gaining popularity in the early 1900s. Modern electronic stenotype machines or programs produce output in written language, which provides an experience similar to other keyboard setups that immediately produce legible work.


Half QWERTY

A half QWERTY keyboard is a combination of an alpha-numeric keypad and a QWERTY keypad, designed for mobile phones. In a half QWERTY keyboard, two characters share the same key, which reduces the number of keys and increases the
surface area The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of ...
of each key, useful for mobile phones that have little space for keys. It means that 'Q' and 'W' share the same key and the user must press the key once to type 'Q' and twice to type 'W'.
