The codes of three input methods are typically printed on the Chinese (traditional) keyboard: Zhuyin (upper right); Cangjie (lower left); and Dayi (lower right). Trilingual editions including either Arabic or Cyrillic also exist. Function- and arrow keys are nearly always present. There is also the Greek 220 layout and the Greek 319 layout.[13]. Functional layout is the arrangement of the key-meaning association or keyboard mapping, determined in software, of all the keys of a keyboard: this (rather than the legends) determines the actual response to a key press. Apple Keyboards do not have the two extra keys. Typically, there are three rows of keys for typing letters and punctuation, an upper row for typing digits and special symbols, and the Space bar on the bottom row. But in general, that’s not the case. Both contain a basic Latin layout in its base and shift states, with a few Latin characters in the AltGr shift states. English is considered a major target as well. Apple supported QZERTY layout in its early Italian keyboards, and currently iPod Touch also has it available.[16]. The spacebar therefore produces a zero width space (non-printable U+200B) for invisible word separation. The Latin alphabet keyboard has a dedicated key for each of the letters A–Z, keys for punctuation and other symbols, usually a row of function keys, often a numeric keypad and some system control keys. The shift key can also be utilized as the shortcut key for the keyboard and can be used in performing various shortcuts. On the basis of this property, the InScript keyboard layout scheme was prepared. Pressing the Han/Eng(한/영) key once switches between Hangul as shown, and QWERTY. There is some variation between different keyboard models in the physical layout – i.e., how many keys there are and how they are positioned on the keyboard. Programs such as the Microsoft Keyboard Layout Creator[67] (basic editor, free, for use on MS Windows), SIL Ukelele[68] (advanced editor, free, for use on Apple's Mac OS X), In addition to the standard 30 letters of the Bulgarian alphabet, the layout includes the non-Bulgarian Cyrillic symbols Э and ы and the Roman numerals I and V (the X is supposed to be represented by the Cyrillic capital Х, which is acceptable in typewriters but problematic in computers). To simplify this, the most common layout for electric typewriters in the United States differed from that for the one most common on manual typewriters. Today the most commonly used layout follows the QWERTY pattern with some changes. Although Khmer has no capital or lowercase, per se, there are two forms for consonants. But there are some other types of keyboards that have different For example, when the ⇧ Shift and numeric 2 keys are pressed simultaneously on a US keyboard; "@" is generated, and the key is engraved appropriately.

There are also variations within these variations; for example the Mac OS X Phonetic Russian layout is YaShERT but differs in placement of ж and э.[85][86]. The more rollover keys a keyboard can handle, the faster the user can type without errors. The use of phonetic-based input method is uncommon due to the lack of official standard for Cantonese romanisation and people in Hong Kong almost never learn any romanisation schemes in schools. [citation needed] Neo is grouped in different layers, each designed for a special purpose. Unlike Azerty, the characters needed for good French typography are easily accessible: for example, the quotation marks (« ») and the curved apostrophe are available directly. Dhivehi Keyboards have two layouts. Various methods have been invented to fit every possibility into a QWERTY keyboard, so East Asian keyboards are essentially the same as those in other countries. Caps lock is usually a shift lock as in AZERTY (see below). The JCUKEN layout was used in the USSR for all computers (both domestically produced and imported such as Japan-made MSX-compatible systems) except IBM-compatible ES PEVM due to its phonetic compatibility with Russian ЙЦУКЕН layout (see right). On Macintosh computers these keys are usually just represented by symbols without the word "Enter", "Shift", "Command", "Option/Alt" or "Control", with the exception of keyboards distributed in the US and East Asia. Examples of these keys include the "comma key," the "question mark key," the "colon key" and the "period key." Even blank keyboards – with no legends – are sometimes used to learn typing skills or by user preference. It is supported by Microsoft Windows (Windows XP SP2 and later only). Numbers are placed on two rows. The overlay was often made from good-quality laminated paper and was designed to fold up and fit in the game's packaging when not in use. Asset,[60] Arensito,[61] Minimak,[62] Norman,[63] Qwpr[64] and Workman[65]); however, none of them are in widespread use, and many of them are merely proofs of concept. The keys are arranged like those of the respective traditional keyboard with a few changes. In other varieties such keys have been translated, like ↵ Intro and ⇪ Bloq mayús, on Spanish computer keyboards respectively for the example above. Two enter keys are located on the keyboard one on the letter side of the keyboard and the other on the numeric pad. For example, in the chorded GKOS keyboard which has been adapted for the Google Android, Apple iPhone, MS Windows Phone, and Intel MeeGo/Harmattan platforms, thumbs are used for chording by pressing one or two keys at the same time. Here’s an example of the keyboard layout on an Apple MacBook Pro: Note that the function keys are smaller than the other keys, and that t… This virtual keyboard[87] offers YaZhERT (яжерт) variant. They can be divided into three main families according to where the A, M, Q, W, Y and Z keys are placed on the keyboard. Without the keyboard you cannot enter your name, address or numbers into the computer. Of the three, Chinese has the most varied input options. Simultaneous input with 無変換 (L Thumb Shift) yields ば, which is the individually mapped letter with the aforementioned dakuten. A Compose key can be characterized as a generic dead key that may in some systems be available instead of or in addition to the more specific dead keys. The AZERTY layout is used in France, Belgium, and some African countries. [20], Colemak variants exist, including Colemak Mod-DH, which seeks to rectify concerns that the layout places too much emphasis on the middle-row centre-column keys (D and H), leading to awkward lateral hand movements for certain common English bigrams such as HE. The positions of the letters are not only optimized for German letter frequency, but also for typical groups of two or three letters. Save my name, email, and website in this browser for the next time I comment. Many keyboards designed for Microsoft Windows have a It is based on ideas from de-ergo and other ergonomic layouts. Instead they are accessed via the numeric keypad or by switching to the Latin character set (on those keyboards without dedicated numeric keys). Sebeolsik Noshift is a variant of sebeolsik which can be used without pressing the shift key. Many high-end keyboards support n-key rollover and so do not have this limitation. The full stop and comma symbols share a key, requiring the shift key to be held to produce a comma, despite the high relative frequency of comma in the language. It is also possible to type kana directly, depending on the mode used. With the advent of the printing telegraph, a keyboard was needed to select characters. The visual layout includes the symbols printed on the physical keycaps. A special button on a computer keyboard that is used for a particular operation in a program. The 104/105-key PC keyboard was born when two ⊞ Win keys and a ≣ Menu key were added on the bottom row (originally for the Microsoft Windows operating system). [5] The U.S. keyboard for the IBM PC, although it resembles the typewriter-pairing standard in most respects, differs in one significant respect: the braces are on the same two keys as the brackets, as their shifts. The layout is right-hand biased with both the vowels and many of the most common consonants on the right side of the layout. Resulting text can then be pasted into other web sites or applications flexibly with no need to reprogram keyboard mappings at all. layouts) or modify existing ones (for example, the The design is so good that anyone could fall in love with the keyboard. Symbols on the keys can be changed dynamically depending on what other keys are pressed, thus eliminating the need to memorize combos for characters and functions before use. For example, the "ISO" keyboard layout is used throughout Europe, but typical French, German, and UK variants of physically identical keyboards appear different because they bear different legends on their keys. . Compared with the secondary-shift modifier key, the dead-key approach may be a little more complicated, but it allows more additional letters. [46][47] Despite the greater efficiency of the Turkish F-keyboard however, the modified QWERTY keyboard ("Q-keyboard") is the one that is used on most computers in Turkey. [13] Microsoft Windows also has Swedish with Sami, Norwegian with Sami and Finnish with Sami layouts, which match the normal Swedish, Norwegian, or Finnish keyboards, but has additional Sami characters as AltGr-combinations. The earliest known implementation of the Cyrillic-to-QWERTY homophonic keyboard was by former AATSEEL officer Constance Curtin between 1972 and 1976, for the PLATO education system's Russian Language curriculum developed at the University of Illinois at Urbana-Champaign. [citation needed] IBM adopted the layout on the PS/2 in 1987 (after previously using an 84-key keyboard which did not have separate cursor and numeric key pads). [79] It superseded the old standard, BDS 5237:1968, on 1 January 1978. Due to the bialphabetic nature of the language, actual physical keyboards with the Serbian Cyrillic layout printed on the keys are uncommon today. It is based on Dr. Kong Byung Woo's earlier work. This keyboard layout had several problems, one of which was the omission of the letter Ґ, which does not exist in Russian. In the keyboard charts listed below, the primary letters or characters available with each alphanumeric key are often shown in black in the left half of the key, whereas characters accessed using the AltGr key appear in blue in the right half of the corresponding key. The multi-touch screens of mobile devices allow implementation of virtual on-screen chorded keyboards. However, Microsoft Windows, which is the most popular operating system used in desktops, does not provide any Cantonese phonetic input method, requiring users to find and install third-party input method software. Physical layout is the actual positioning of keys on a keyboard. A dead key is a special kind of a modifier key that, instead of being held while another key is struck, is pressed and released before the other key. The Russian Typewriter layout can be found on many Russian typewriters produced before the 1990s, and it is the default Russian keyboard layout in the OpenSolaris operating system.[82]. Types Of Mechanical Keys- Design Of Keys, Keyways Introduction To Mechanical Key: A key is the piece inserted in an axial direction between a shaft and hub of the mounted machine element such as pulley or gear etc., This allowed the user to type over 8000 possible characters by playing suitable "chords" with many modifier keys pressed simultaneously. Typing, function, control and numeric keys are the main ones. A similar concept was followed to research and develop the MessagEase keyboard layout for fast text entry with stylus or finger. The Greek Polytonic layout has various dead keys to input the accented letters. Computer keyboard keys are arranged in four major groups. This key is an alternative key for pressing the ok button on the screen and is used for entry of the desired process.

The images of AATSEEL "Student", YaZhERT (яжерт) and YaWERT (яверт) are shown on this page. The most extreme example of such a keyboard, the so-called "Space-cadet keyboard" found on MIT LISP machines, had no fewer than seven modifier keys: four control keys, Ctrl, Meta, Hyper, and Super, along with three shift keys, ⇧ Shift, Top, and Front. There are 26 alphabet keys from a to z with the help of which you can type any text or word from the document.

Thus the Workman layout allots a lower priority to the two innermost columns between the home keys (G and H columns on a QWERTY layout), similarly to the Colemak-DH or "Curl" mods. The positioning of the character keys is similar to the keyboard of a typewriter. It shares several design goals with the Dvorak layout, such as minimizing finger path distance and making heavy use of the home row. Windows 10 includes its own implementation of a mnemonic QWERTY-based input method for Russian, which does not fully rely on assigning a key to every Russian letter, but uses the sh, sc, ch, ya (ja), yu (ju), ye (je), yo (jo) combinations to input ш, щ, ч, я, ю, э, and ё respectively. Sámi keyboards use a layout known as the Sámi Extended, where Á appears in place of Q above A, Š appears in place of W above S, Č appears in place of X to the left of C, and Ŧ appears in place of Y to the right of T, with Q, W, X, and Y being available by use of the AltGr key. For example, as of May 2008[update], Apple Inc produces ISO, ANSI, and JIS desktop keyboards, each in both extended and compact forms. Latin American Extended[74] or You can also find another numeric keypad on the right side of the keyboard, however, it depends upon the keyboard model and in … For example, striking Compose followed by ' (apostrophe) and then A results in á (a with acute accent), Compose followed by A and then E results in æ (ae ligature), and Compose followed by O and then C results in © (circled c, copyright symbol). While the central area of the keyboard, the alphabetic section, remains fairly constant, and the numbers from 1–9 are almost invariably on the row above, keyboards may differ in: The physical keyboard is of the basic ISO, ANSI, or JIS type; pressing a key sends a scan code to the operating-system or other software, which in turn determines the character to be generated: this arrangement is known as the keyboard mapping. It is more ergonomic than the dubeolsik, but is not in wide use. The current official Bulgarian keyboard layout for both typewriters and computer keyboards is described in BDS (Bulgarian State/National Standard) 5237:1978. In Canada, the CSA keyboard is designed to write several languages, especially French. It can be used to type an extra symbol in addition to the two otherwise available with an alphanumeric key, and using it simultaneously with the ⇧ Shift key usually gives access to a fourth symbol. Although there are a large number of keyboard layouts used for languages written with Latin-script alphabets, most of these layouts are quite similar. The Workman layout is found to achieve overall less travel distance of the fingers for the English language than even Colemak. [13], Turkmen keyboards use a layout known as ÄWERTY, where Ä appears in place of Q above A, Ü appears in place of X below S, Ç appears in place of C, and Ý appears in place of V, with C, Q, V, and X not being accessible at all.

Western and Eastern Armenian have different layouts. As noted before, the layout of a keyboard may refer to its physical (arrangement of keys), visual (physical labeling of keys), or functional (software response to a key press or release) layout. This layout is notable for its compatibility with the QWERTY layout; almost all QWERTY symbols that are not alphanumeric are available in Hangul mode. 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, not the specific character engraved on that key. This alternative was not supported until Windows Vista.[13]. All but one (ឡ) have a second, "subscript", form to be used when it occurs as the second (or, rarely, third) letter in a consonant cluster. They keys are perform specific tasks. This may be done through a special key on the keyboard devoted to this task, or through some special combination of keys, or through software programs that do not interact with the keyboard much.

The extra keys in the bottom row (muhenkan, henkan, and the Hiragana/Katakana switch key), and the special keys in the leftmost column (the hankaku/zenkaku key at the upper left corner, and the eisū key at the Caps Lock position), control various aspects of the conversion process and select different modes of input. Specifically, the index finger prefers to curl inwards rather than stretch outwards. Other than this, special feature keys are incorporated in some modern keyboards. A computer or standard typewriter keyboard, on the other hand, has four banks of keys, with home row being second from bottom. For example, the Kinesis Advantage contoured keyboard allows for reprogramming single keys (not key combinations), as well as creating macros for remapping combinations of keys (this however includes more processing from the keyboard hardware, and can therefore be slightly slower, with a lag that may be noticed in daily use). After finally deciding to go for a mechanical keyboard, another question usually comes up very soon: Which switch type do you want to use? The Armenian keyboard is similar to the Greek in that in most (but not all) cases, a given Armenian letter is at the same location as the corresponding Latin letter on the QWERTY keyboard. 10 Different Types Of Computer Keyboard Available In The Market These days, there are different types of keyboards readily available in the market which is suitable for different kind of users.
