Compose Key
A compose key (sometimes called multi key) is a key on a computer keyboard that indicates that the following (usually 2 or more) keystrokes trigger the insertion of an alternate character, typically a precomposed character or a symbol. For instance, typing followed by and then will insert ñ. Compose keys are most popular on Linux and other systems using the X Window System, but software exists to implement them on Microsoft Windows, Windows and macOS. History The Compose Character key was introduced by engineers at Digital Equipment Corporation (DEC) on the LK201 keyboard, available since 1983 with the VT220 terminal. The keyboard included an LED indicating that a Compose sequence is on-going. While the LK201 introduced the group of command keys between the alphanumerical block and the numerical keypad, and the "inverted T" arrangement of arrow keys, which have become standard, the compose key by contrast did not become a standard. In 1987, Sun Microsystems released the Sun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XFCE4 Compose Key Selection
Xfce or XFCE (pronounced as four individual letters, ) is a free and open-source desktop environment for Linux and other Unix-like operating systems. Xfce aims to be fast and lightweight while still visually appealing and easy to use. The desktop environment is designed to embody the traditional Unix philosophy of modularity and re-usability, as well as adherence to standards; specifically, those defined at freedesktop.org. Features User experience Xfce is a highly modular desktop environment, with many software repositories separating its components into multiple packages.

Key Rollover
Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with ''n''-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed. Keyboards that lack full rollover will register an incorrect keystroke when certain combinations of keys are pressed simultaneously. Rollover has applications for stenotype, electronic music keyboards, gaming, and touch-typing generally. Keyboard usage During normal typing on a conventional computer keyboard, only one key is usually pressed at any given time, then released before the next key is pressed. However, this is not always the case. When using modifier keys such as Shift or Control, the user intentionally holds the modifier key(s) while pressing and releasing another key. Rapid typists may also sometimes inadvertently press a key before releasing the previous one. Certain unusual forms of keyboard ...

Alt Code
On personal computers with numeric keypads that use Microsoft operating systems, such as Windows, many characters that do not have a dedicated key combination on the keyboard may nevertheless be entered using the Alt code (the Alt numpad input method). This is done by pressing and holding the key, then typing a number on the keyboard's numeric keypad that identifies the character and then releasing . MS-DOS On IBM PC compatible personal computers from the 1980s, the BIOS allowed the user to hold down the key and type a decimal number on the keypad. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke. Applications reading keystrokes from the BIOS would behave according to what action they associate with that code. Some would interpret the code as a command, but often it would be interpreted as an 8-bit character from the current code page that was inserted into the text the user was ...

Two Dots (diacritic)
Diacritical marks of two dots , placed side-by-side over or under a letter, are used in several languages for several different purposes. The most familiar to English language, English-language speakers are the Diaeresis (diacritic), diaeresis and the Umlaut (diacritic), umlaut, though there are numerous others. For example, in Albanian language, Albanian, represents a schwa. Such diacritics are also sometimes used for stylistic reasons (as in the family name Brontë family, Brontë or the band name Mötley Crüe). In modern computer systems using Unicode, the two-dot diacritics are almost always character encoding, encoded identically, having the same code point. For example, represents both ''o-umlaut'' and ''o-diaeresis''. Their appearance in print or on screen may vary between typefaces but rarely within the same typeface. The word ''wikt:trema, trema'' (), used in linguistics and also Classics, classical scholarship, describes the form of both the umlaut diacritic and the ...

Backtick
The backtick is a typographical mark used mainly in computing. It is also known as backquote, grave, or grave accent. The character was designed for typewriters to add a grave accent to a (lower-case) base letter, by overtyping it atop that letter. On early computer systems, however, this physical dead key+overtype function was rarely supported, being functionally replaced by precomposed characters. Consequently, this ASCII symbol was rarely (if ever) used in computer systems for its original aim and became repurposed for many unrelated uses in computer programming. The sign is located on the left-top of a US or UK layout keyboard, next to the key. Provision (if any) of the backtick on other keyboards varies by national keyboard layout and keyboard mapping. History Typewriters On typewriters designed for languages that routinely use diacritics (accent marks), there are two possible solutions. Keys can be dedicated to pre-composed characters or alternatively a dead key mechani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diacritic
A diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek (, "distinguishing"), from (, "to distinguish"). The word ''diacritic'' is a noun, though it is sometimes used in an attributive sense, whereas ''diacritical'' is only an adjective. Some diacritics, such as the acute , grave , and circumflex (all shown above an 'o'), are often called ''accents''. Diacritics may appear above or below a letter or in some other position such as within the letter or between two letters. The main use of diacritics in Latin script is to change the sound-values of the letters to which they are added. Historically, English has used the diaeresis diacritic to indicate the correct pronunciation of ambiguous words, such as "coöperate", without which the letter sequence could be misinterpreted to be pronounced . Other examples are the acute and grave accents, which can indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottish Gaelic
Scottish Gaelic (, ; Endonym and exonym, endonym: ), also known as Scots Gaelic or simply Gaelic, is a Celtic language native to the Gaels of Scotland. As a member of the Goidelic language, Goidelic branch of Celtic, Scottish Gaelic, alongside both Irish language, Irish and Manx language, Manx, developed out of Old Irish. It became a distinct spoken language sometime in the 13th century in the Middle Irish period, although a Classical Gaelic, common literary language was shared by the Gaels of both Ireland and Scotland until well into the 17th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language place names. In the 2011 United Kingdom census#2011 Census for Scotland, 2011 census of Scotland, 57,375 people (1.1% of the Scottish population, three years and older) reported being able to speak Gaelic, 1,275 fewer than in 2001. The highest percentages of Gaelic speakers were in the Outer Hebrides. Nevertheless, there is a language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Language
Irish (Standard Irish: ), also known as Irish Gaelic or simply Gaelic ( ), is a Celtic language of the Indo-European language family. It is a member of the Goidelic languages of the Insular Celtic sub branch of the family and is indigenous language, indigenous to the island of Ireland. It was the majority of the population's first language until the 19th century, when English (language), English gradually became dominant, particularly in the last decades of the century, in what is sometimes characterised as a result of linguistic imperialism. Today, Irish is still commonly spoken as a first language in Ireland's Gaeltacht regions, in which 2% of Ireland's population lived in 2022. The total number of people (aged 3 and over) in Ireland who declared they could speak Irish in April 2022 was 1,873,997, representing 40% of respondents, but of these, 472,887 said they never spoke it and a further 551,993 said they only spoke it within the education system.

AltGr
AltGr (also Alt Graph) is a modifier key found on computer keyboards. It is primarily used to type characters that are used less frequently in the language that the keyboard is designed for, such as foreign currency symbols, typographic marks and accented letters. The AltGr key is used to access a third and a fourth grapheme for most keys. Most are accented variants of the letters on the keys, but some are additional symbols and punctuation marks. For example, when the US-International keyboard mapping is active, the key can be used to insert four different characters: * → c (lowercase — first level) * → C (uppercase — second level) * → © ( copyright sign — third level) * → ¢ ( cent sign — fourth level) Some languages, such as Bengali, use this key when the number of letters of their alphabet is too large for a standard keyboard. On keyboard layouts that do not include an AltGr key, such as US keyboards, the key position is labelled as a right-hand A ...

Mnemonic
A mnemonic device ( ), memory trick or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember. It makes use of elaborative encoding, retrieval cues and imagery as specific tools to encode information in a way that allows for efficient storage and retrieval. It aids original information in becoming associated with something more accessible or meaningful—which in turn provides better retention of the information. Commonly encountered mnemonics are often used for lists and in auditory system, auditory form such as Acrostic, short poems, acronyms, initialisms or memorable phrases. They can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous and otherwise "relatable" information rather tha ...

Copyright Symbol
The copyright symbol, or copyright sign, (a circled capital letter C for copyright), is the symbol used in copyright notices for works other than sound recordings. 17 U.S.C. The use of the symbol is described by the Universal Copyright Convention. The symbol is widely recognized but, under the Berne Convention, is no longer required in most nations to assert a new copyright. US law In the United States, the Berne Convention Implementation Act of 1988, effective March 1, 1989, removed the requirement for the copyright symbol from U.S. copyright law, but its presence or absence is legally significant on works published before that date, and it continues to affect remedies available to a copyright holder whose work is infringed. History Prior symbols indicating a work's copyright status are seen in Scottish almanacs of the 1670s; books included a printed copy of the local coat-of-arms to indicate their authenticity. A copyright notice was first required in the U.S. by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
