  • 1) What kind of keyboard? "Keyboard may refer to: Alphanumeric keyboard Keyboard (computing), a set of alphanumeric and command keys used to input information to a computer IBM PC keyboard Apple Keyboard Chorded keyboard, on which several keys are pressed together to enter a letter or command - In music: Musical keyboard, a set of adjacent keys or levers used to play a musical instrument Keyboard instrument, an instrument with a musical keyboard (see above) Electronic keyboard, a keyboard instrument (see above) in which key presses complete an electric circuit Keyboard controller, an electronic keyboard used to send MIDI data to a computer or synthesizer See sub-articles for various other types, including digital pianos, synthesizers, electric organs, etc. Pedal keyboard, a foot-operated keyboard that is placed on the floor Keyboardist, a musician who plays keyboard instruments Keyboard Magazine, a publication about musical instruments such as the piano" Source and further information: 2) Computer keyboards: "- Standard: Standard keyboards for desktop computers, such as the 101-key US traditional keyboards or the 104-key Windows keyboards, include alphabetic characters, punctuation symbols, numbers and a variety of function keys. The internationally-common 102/105 key keyboards have a smaller 'left shift' key and an additional key with some more symbols between that and the letter to its right (usually Z or Y) - Laptop-size: Keyboards on laptops and notebook computers usually have a shorter travel distance for the keystroke and a reduced set of keys. As well, they may not have a numerical keypad, and the function keys may be placed in locations that differ from their placement on a standard, full-sized keyboard. - Gaming and multimedia: Keyboards with extra keys, such as multimedia keyboards, have special keys for accessing music, web and other frequently used programs and. For example, 'ctrl+marked on color-coded keys are used for some software applications and for specialized uses video editing. - Thumb-sized: Smaller keyboards have been introduced for laptops, PDAs, cellphones or users who have a limited workspace. The size of a standard keyboard is dictated by the practical consideration that the keys must be large enough to be easily pressed by fingers. To reduce the size of the keyboard, the numeric keyboard to the right of the alphabetic keyboard can be removed, or the size of the keys can be reduced, which makes it harder to enter text. Another way to reduce the size of the keyboard is to reduce the number of keys and use chording keyer, i.e. pressing several keys simultaneously. For example, the GKOS keyboard has been designed for small wireless devices. Other two-handed alternatives more akin to a game controller, such as the AlphaGrip, are also used as a way to input data and text. Another way to reduce the size of a keyboard is to use smaller buttons and pack them closer together. Such keyboards, often called a "thumbboard" (thumbing) are used in some personal digital assistants such as the Palm Treo and BlackBerry and some Ultra-Mobile PCs such as the OQO. - Numeric: Numeric keyboards contain only numbers, mathematical symbols for addition, subtraction, multiplication, and division, a decimal point, and several function keys (e.g. End, Delete, etc.). They are often used to facilitate data entry with smaller keyboard-equipped laptops or with smaller keyboards that do not have a numeric keypad. A laptop does sometimes have a numeric pad, but not all the time. These keys are also known as, collectively, a numeric pad, numeric keys, or a numeric keypad, and it can consist of the following types of keys: arithmetic operators such as +, -, *, / numeric digits 0-9 cursor arrow keys navigation keys such as Home, End, PgUp, PgDown, etc. Num Lock button, used to enable or disable the numeric pad" Source and further information: 3) Musical keyboards: "The chromatic compass of keyboard instruments has tended to increase. Harpsichords often extended over five octaves (61+ keys) in the 18th century, while most pianos manufactured since about 1870 have 88 keys. Some modern pianos have even more notes (a Bösendorfer 225 has 92 and a Bösendorfer 290 "Imperial" has 97 keys). While modern synthesizer keyboards commonly have either 61, 76 or 88 keys, small MIDI controllers are available with 25 notes. Organs normally have 61 keys per manual, though some spinet models have 44 or 49. An organ pedalboard is a keyboard with long pedals which are played by the organist's feet. Pedalboards vary in size from 12 to 32 notes." Source and further information:
