context: QWERTY QWERTY (, ) is a keyboard design for Latin-script alphabets. The name comes from the order of the first six keys on the top left letter row of the keyboard ( ). The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to E. Remington and Sons in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in widespread use.

The keyboard and the computer each have no information about what is marked on that key, and it could equally well be the letter "A" or the digit "9". The user of the computer is requested to identify the "functional layout" of the keyboard when installing the operating system. Today, most keyboards use one of three different mechanical layouts, usually referred to as simply "ISO" (ISO/IEC 9995-2), "ANSI" (ANSI-INCITS 154-1988), and "JIS" (JIS X 6002-1980), referring roughly to the </s> notes (a Bösendorfer 290 "Imperial" has 97 keys and a Stuart & Sons model has 108 keys). While modern synthesizer keyboards commonly have either 61, 76 or 88 keys, small MIDI controllers are available with 25 notes. (Digital systems allow shifting octaves, pitch, and "splitting" ranges dynamically, reducing the need for dedicated keys.) Organs normally have 61 keys per manual, though some spinet models have 44 or 49. An organ pedalboard is a keyboard with long pedals played by the organist's feet. Pedalboards vary in size from 12 to 32 notes. In a typical keyboard layout, "black note" keys have
