Some keyboard layouts for non-Latin alphabetic scripts, most notably the Greek layout, are based on the QWERTY layout, in that glyphs are assigned as far as possible to keys that bear similar-sounding or appearing glyphs in QWERTY. These are the keys that are present on the top of the keyboard and these functions keys have a predefined function. Inuktitut has two similar, though not identical, commonly available keyboard layouts for Windows. [28], Other layouts lay importance on minimal key deviation from QWERTY to give a reasonable increase in typing speed and ergonomics with minimal relearning of keys.[29]. Keyboard layout in this sense may refer either to this broad categorization or to finer distinctions within these categories. As mentioned, there are keyboards referred to as Full-Size (101/102/104/105 keys) and there are keyboards called Tenkeyless (87/88) where the number pad is dropped. The dead key does not generate a character by itself, but it modifies the character generated by the key struck immediately after, typically making it possible to type a letter with a specific diacritic. They are named after the first several letters that take over the 'QWERTY' row on the Latin keyboard.

Apart from typing numbers and symbols, keyboards can also be used to perform special operations. The UNIX keyboard layout also differs in the placement of the ESC key, which is to the left of 1. Read more about PC Although it has been demonstrated that the QWERTY layout is not the most efficient layout for typing,[4] it remains the standard. Peter Zelchenko worked under Curtin at UIUC, and his later modifications to the number row for Windows and Macintosh keyboards follow Curtin's original design intent.[84]. [42], In 2019, a slightly modified version of the BÉPO layout is featured in a French standard developed by AFNOR, along with an improved version of the traditional AZERTY layout. Transliteration is one example of that whereby letters in other language get matched to visible Latin letters on the keyboard by the way they sound.

When the keys on a keyboard don't work, it's usually due to mechanical failure. The Workman layout is found to achieve overall less travel distance of the fingers for the English language than even Colemak. 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]. Many Unix workstations (and also home computers like the Amiga) keyboards placed the Ctrl key to the left of the letter A, and the ⇪ Caps Lock key in the bottom left. Of the three, Chinese has the most varied input options. Although there are a large number of keyboard layouts used for languages written with Latin-script alphabets, most of these layouts are quite similar. [33] This 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. Usually the functional layout is set to match the visual layout of the keyboard being used, so that pressing a key will produce the expected result, corresponding to the legends on the keyboard. There are actually three different PC keyboards: the original PC keyboard with 84 keys, the AT keyboard also with 84 keys and the enhanced keyboard with 101 keys. 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. In the pre-computer times Armenian keyboards had quite a different layout, more suitable for producing letter combinations inherent to the language. These statistics were then combined with studies on bone and muscle anatomy of the fingers to design the Turkish F-keyboard (Turkish: F klavye). Simultaneous input with 無変換 (L Thumb Shift) yields ば, which is the individually mapped letter with the aforementioned dakuten. 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).

Some manufacturers although, chose to link the switch color with the background color in some of their keyboards. Typical keyboards sold in Serbian-speaking markets are marked with Serbian Latin characters and used with both the Latin (QWERTZ) and Cyrillic layout configured in the software. The layout is right-hand biased with both the vowels and many of the most common consonants on the right side of the layout. The most common choice is to not include the numpad, which can usually be fully replaced by the alphanumeric section. Both are supported by Microsoft Windows (Windows XP and later only).[13]. The keys are arranged like those of the respective traditional keyboard with a few changes. The QZERTY layout was used mostly in Italy, where it was the traditional typewriter layout. Vowels are in the middle. Depending on operating systems, various application programs are available to create, add and switch among keyboard layouts. Certain virtual keyboards and keyboard layouts are accessible online. 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). For example, on some keyboard layouts, the grave accent key ` is a dead key: in this case, striking ` and then A results in à (a with grave accent); ` followed by ⇧ Shift+E results in È (E with grave accent). There is also a set of several keys present on the right side of the keyboard for typing numbers. Alphabetical, numeric, and punctuation keys are used in the same fashion as a typewriter keyboard to enter their respective symbol into a word processing program, text editor, data spreadsheet, or other program. There are several kana-based typing methods. This means that a physical keyboard may be dynamically mapped to any layout without switching hardware components – merely by changing the software that interprets the keystrokes. For Chinese input, Shape-based input methods such as Cangjie (pronounced as ChongKit in Cantonese) or Chinese handwriting recognition are the most common input method. However, sometimes non-functioning keys can be fixed. Most modern input methods allow input of both simplified and traditional characters, and will simply default to one or the other based on the locale setting. In countries using the Latin script, the center, alphanumeric portion of the modern keyboard is most often based on the QWERTY design by Christopher Sholes, who laid out the keys in such a way that common two-letter combinations were placed on opposite sides of the keyboard so that his mechanical keyboard would not jam, and laid out the keys in rows offset horizontally from each other by three-eighths, three-sixteenths, and three-eighths inches to provide room for the levers. The shape of the keys and the feel under your fingertips have been taken more seriously over the years by keyboard manufacturers, although, choosing from the different types is purely based on personal preference. This method is the fastest because it has the capability to fetch the exact, unambiguous Chinese character which the user has in mind to input, pinpointing to only one character in most cases. It is more ergonomic than the dubeolsik, but is not in wide use.
