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 ...

Keyboard Layout
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. Standard keyboard layouts vary depending on their intended writing system, language, and use case, and some hobbyists and manufacturers create non-standard layouts to match their individual preferences, or for extended functionality. is the actual positioning of keys on a keyboard. is the arrangement of the legends (labels, markings, engravings) that appear on those keys. is the arrangement of the key-meaning association or keyboard mapping, determined in software, of all the keys of a keyboard; it is this (rather than the legends) that determines the actual response to a key press. Modern computer keyboards are designed to send a scancode to the operating system (OS) when a key is pressed or released. This code reports only the key's row and column ...

Dead Key
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 (alphabet), letter. The dead key does not generate a (complete) grapheme, 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. For example, if a keyboard mapping (such as US international) has a dead key for the circumflex, , the character can be generated by first pressing and then . Usually, the diacritic itself can be generated as a free-standing character by pressing the dead key followed by ''space''; so a caret (free-standing circumflex) can be typed by pressing and then . Mechanical typewriters The dead key is mechanical in origin, and "dead" means without movement. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modifier Key
In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together. By themselves, modifier keys usually do nothing; that is, pressing any of the , , or keys alone does not (generally) trigger any action from the computer. They are commonly used in defined sequences of keys with another keys to trigger a specific action. These sequences are called keyboard shortcuts. For example, in most keyboard layouts the Shift key combination will produce a capital letter "A" instead of the default lower-case letter "a" (unless in Caps Lock or Shift lock mode). A combination of in Microsoft Windows will trigger the shortcut for closing the active window; in this instance, Alt is the modifier key. In contrast, pressing just or will probably do nothing unless assigned a specific function in a particular program (for example, activating input aids or the toolbar of the active window in Windo ...

Computer Keyboard
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or Push-button, keys to act as Mechanical keyboard, mechanical levers or Electronic switching system, electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input device, input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Keyboard keys (buttons) typically have a set of characters Engraving, engraved or Printing, printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce character (computing), characters (Letter (alphabet), letters, Numerical digit, numbers or symbols), other keys (such as the escape key) can prompt the ...

Option Key
The Option key, , is a modifier key present on Apple keyboards. It is located between the Control key and the Command key on a typical Mac keyboard. There are two Option keys on modern (as of 2020) Mac desktop and notebook keyboards, one on each side of the space bar. (As of 2005, some laptops had only one, in order to make room for the arrow keys.) Apple Inc., Apple commonly uses the symbol to represent the Option key. From 1980 to 1984, on the Apple II, this key was known as the closed apple key or the solid apple key, and had a black line drawing of a filled-in on it. Since the 1990s, "Alt" has sometimes appeared on the key as well, for use as an Alt key with non-Mac software, such as Unix and Windows programs; as of 2017, the newest Apple keyboards such as the Magic Keyboard (Mac), Magic Keyboard no longer include the "Alt" label. The Option key in a Mac operating system functions differently from the Alt key under other Unix-like systems or Microsoft Windows. It is not us ...

Alt Key
The Alt key (pronounced or ) on a computer keyboard is used to change (alternate) the function of other pressed keys. Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. For example, simply pressing ''A'' will type the letter 'a', but holding down the Alt key while pressing ''A'' will cause the computer to perform an function, which varies from Computer program, program to program. The international standard ISO/IEC 9995-2 calls it ''Alternate key''. The key is located on either side of the space bar, but in non-US PC keyboard layouts, rather than a second Alt key, there is an 'AltGr key, Alt Gr' key to the right of the space bar. Both placements are in accordance with ISO/IEC 9995-2. With some keyboard mappings (such as US-International), the right Alt key can be reconfigured to function as an AltGr key although not engraved as such. The standardized keyboard symbol for the Alt key, (which may be used when the usual Latin lettering "Alt" is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AZERTY
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, ( ). Like other European keyboard layouts, it is modelled on the English-language QWERTY layout. It is used in France and Belgium, though both countries have their own national variation on the layout. The competing layouts devised for French (e.g. the 1907 ZHJAY layout, Claude Marsan's 1976 layout, the 2002 Dvorak-fr, and the 2005 BÉPO layout) have obtained only limited recognition, although the latter has been included in the 2019 French keyboard layout standard. History The AZERTY layout appeared in France in the last decade of the 19th century as a variation on American QWERTY typewriters. Its exact origin is unknown. It was more successful than its contemporaries (e.g. the French ZHJAYS layout created by Albert Navarre in the early 20th cen ...

Shift Key
The Shift key is a modifier key on a alphanumeric keyboard, keyboard, used to type majuscule, capital letters and other alternate "upper" characters. There are typically two Shift keys, on the left and right sides of the row below the home row. The Shift key's name originated from the typewriter, where one had to press and hold the button to shift up the case stamp to change to capital letters; the Shift key was first used in the E. Remington and Sons, Remington No. 2 Type-Writer of 1878; the No. 1 model was capital-only. On the Keyboard layout#QWERTY, US layout and similar keyboard layouts, characters that typically require the use of the Shift key include the bracket, parentheses, the question mark, the exclamation point, and the colon (punctuation), colon. When the Caps Lock key is engaged, the Shift key may be used to type lowercase letters on many operating systems, though not on macOS or on Microsoft Windows keyboard layouts that have the SGCAPS feature.

Box-drawing Characters
Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment. Box-drawing characters therefore typically only work well with monospaced fonts. In graphical user interfaces, these characters are much less useful as it is simpler to draw lines and rectangles directly with graphical APIs. However, they are still useful for command-line interfaces and plaintext Comment (computer programming), comments within source code. Some recent embedded systems also use proprietary character sets, usually extensions to ISO 8859 character sets, which include box-drawing characters or other special symbols. Other types of box-drawing characters are block elements, shade characters, and terminal graphic characters; these can be used ...
