QWERTY is a keyboard layout for Latin-script alphabets. The name comes from the order of the first six keys on the top letter row of the keyboard: QWERTY. The QWERTY design is based on a layout included in the Sholes and Glidden typewriter sold via E. Remington and Sons from 1874. QWERTY became popular with the success of the Remington No. 2 of 1878 and remains in ubiquitous use.
Ü is a Latin script character composed of the letter U and the diaeresis diacritical mark. In some alphabets such as those of a number of Romance languages or Guarani it denotes an instance of regular U to be construed in isolation from adjacent characters with which it would usually form a larger unit; other alphabets like the Azerbaijani, Estonian, German, Hungarian and Turkish ones treat it as a letter in its own right. In those cases it typically represents a close front rounded vowel.
The QWERTZ or QWERTZU keyboard is a typewriter and keyboard layout widely used in Central and Southeast Europe. The name comes from the first six letters at the top left of the keyboard:.
AZERTY is a specific layout for the characters of the Latin alphabet on typewriter keys and computer keyboards. The layout takes its name from the first six letters to appear on the first row of alphabetical keys; that is,. Similar to the QWERTZ layout, it is modelled on the English QWERTY layout. It is used in France and Belgium, although each of these countries has its own national variation on the layout. Luxembourg and Switzerland use the Swiss QWERTZ keyboard. Most residents of Quebec, the mainly French-speaking province of Canada, use a QWERTY keyboard that has been adapted to the French language such as the Multilingual Standard keyboard CAN/CSA Z243.200-92 which is stipulated by the government of Quebec and the Government of Canada.
A dead key is a special kind of modifier key on a mechanical typewriter, or computer keyboard, that is typically used to attach a specific diacritic to a base letter. The dead key does not generate a (complete) character by itself, but modifies the character generated by the key struck immediately after. Thus, a dedicated key is not needed for each possible combination of a diacritic and a letter, but rather only one dead key for each diacritic is needed, in addition to the normal base letter keys.
The palochka is a letter in the Cyrillic script. The letter is usually caseless. It was introduced in the late 1930s as the Hindu-Arabic digit '1', and on Cyrillic keyboards, it is usually typeset as the Roman numeral 'I'. Unicode currently supports both caseless/capital palochka at U+04C0 and a rarer lower-case palochka at U+04CF. The palochka marks glottal(ized) and pharyngeal(ized) consonants.
Caps Lock⇪ Caps Lock is a button on a computer keyboard that causes all letters of bicameral scripts to be generated in capital letters. It is a toggle key: each press reverses the previous action. Some keyboards also implement a light to give visual feedback about whether it is on or off. Exactly what Caps Lock does depends on the keyboard hardware, the operating system, the device driver, and the keyboard layout. Usually, the effect is limited to letter keys. Letters of non-bicameral scripts and non-letter characters are generated normally.
The numero sign or numero symbol, № (also represented as Nº, No̱, No. or no.), is a typographic abbreviation of the word number(s) indicating ordinal numeration, especially in names and titles. For example, using the numero sign, the written long-form of the address "Number 29 Acacia Road" is shortened to "№ 29 Acacia Rd", yet both forms are spoken long.
AltGr is a modifier key found on many computer keyboards. It is primarily used to type special characters and symbols that are not widely used in the territory where sold, such as foreign currency symbols, typographic marks and accented letters. On a typical Windows-compatible PC keyboard, the AltGr key, when present, takes the place of the right-hand Alt key. The key at this location will operate as AltGr if a keyboard layout using AltGr is chosen in the operating system, regardless of what is engraved on the key. In macOS, the Option key has functions similar to the AltGr key.
There are two major English language computer keyboard layouts, the United States layout and the United Kingdom layout defined in BS 4822. Both are QWERTY layouts. Users in the United States do not frequently need to make use of the £ (pound) and € (euro) currency symbols, which are common needs in the United Kingdom and Ireland, although the $ symbol is also provided as standard on UK and Irish keyboards. In other countries which predominantly use English as a common working language, such as Australia, Canada, and New Zealand, the US keyboard is commonly used.
Japanese input methods are used to input Japanese characters on a computer.
Diacritical marks of two dots¨, placed side-by-side over or under a letter, are used in a number of languages for several different purposes. The most familiar to English-language speakers are the diaeresis and the umlaut, though there are numerous others. For example, in Albanian, ë represents a schwa. Such diacritics are also sometimes used for stylistic reasons.
A Hebrew keyboard comes in two different keyboard layouts. Most Hebrew keyboards are bilingual, with Latin characters, usually in a US Qwerty layout. Trilingual keyboard options also exist, with the third script being Arabic or Russian, due to the sizable Arabic- and Russian-speaking populations in Israel.
ISO/IEC 9995Information technology — Keyboard layouts for text and office systems is an ISO/IEC standard series defining layout principles for computer keyboards. It does not define specific layouts but provides the base for national and industry standards which define such layouts.
JCUKEN is the main Cyrillic keyboard layout for the Russian language in computers and typewriters. Earlier in Russia JIUKEN (ЙІУКЕН) layout was the main layout, but it was replaced by JCUKEN when the Russian alphabet reform of 1917 removed the letters Ѣ, І, Ѵ, and Ѳ. The letter Ъ had decreased in usage significantly after the reform.
A keyboard layout is any specific physical, visual, or functional arrangement of the keys, legends, or key-meaning associations (respectively) of a computer keyboard, mobile phone, or other computer-controlled typographic keyboard.
A bit-paired keyboard is a keyboard where the layout of shifted keys corresponds to columns in the ASCII (1963) table, archetypally the Teletype Model 33 (1963) keyboard. This was later contrasted with a typewriter-paired keyboard, where the layout of shifted keys corresponds to electric typewriter layouts, notably the IBM Selectric (1961). The difference is most visible in the digits row : compared with mechanical typewriters, bit-paired keyboards remove the _ character from 6 and shift the remaining &* from 7890 to 6789, while typewriter-paired keyboards replace 3 characters: ⇧ Shift+2 from " to @⇧ Shift+6 from _ to ^ and ⇧ Shift+8 from ' to *. An important subtlety is that ASCII was based on mechanical typewriters, but electric typewriters became popular during the same period that ASCII was adopted, and made their own changes to layout. Thus differences between bit-paired and (electric) typewriter-paired keyboards are due to the differences of both of these from earlier mechanical typewriters.
The Vietnamese language is written with a Latin script with diacritics which requires several accommodations when typing on phone or computers. Software-based systems are a form of writing Vietnamese on phones or computers with software that can be installed on the device or from third-party software such as UniKey. Telex is the oldest input method devised to encode the Vietnamese language with its tones. Other input methods may also include VNI and VIQR. VNI input method is not to be confused with VNI code page.
There are a number of methods to input Esperanto letters and text on a computer, e.g. when using a word processor or email. Input methods depend on a computer's operating system. Specifically the characters ĵ, ĝ, ĉ, ĥ, ŭ, ŝ can be problematic.
