A scancode is in strict terms an index that corresponds to the position a key has in a keyboard's internal keyboard matrix.

In IBM PC parlance, the term is also used for keys over the wire and within operating systems — because originally the mapping was direct to the matrix. It is also often sloppily used to name entire key event codes, or code sequences.

Most operating systems outside the PC use the term key code or virtual key code for key numbers. In USB parlance, the term for key number is usage code, and these are grouped in code pages. USB's Human Interface Device (HID) subprotocol uses usage codes not just for keys but for all types of controls and e.g. logical grouping and for signalling error conditions. Because USB HID sends status reports (not events), a key is represented by its usage code being either present (or bit set) or not present (or bit cleared).

IBM PC scancodes

Scancodes in Set 1 were used over the XT keyboard interface. They are still in use internally on systems with IBM PC lineage such as MS Windows and Linux ("raw mode").

Scancodes in Set 2 are used in the protocol used by the AT and PS/2 interfaces.

Scancodes in Set 3 are used in the keyboard protocol for terminals from IBM.

History

The IBM PC/XT protocol's scancodes corresponded directly to key positions when scanning the original IBM PC/XT keyboard's matrix. A single bit in the byte sent over the wire distinguishes between a key press (make) or key release event (break). Raw scancode bytes were delivered to programs by the BIOS.

The later protocol used by AT and PS/2 interfaces uses the different set 2 of code sequences over the wire. For the IBM PC/AT to remain backwards-compatible, XT scancodes were not only presented to programs by the BIOS but there was also a special microcontroller which converted the new Set 2 codes back to the old Set 1 codes for badly written programs that accessed the hardware directly.

However, with this backwards compatibility came added complexity. The IBM Enhanced Keyboard (Model M) introduced even more additional keys. Pressing some keys can produce quite long sequences to be sent, especially with modifiers. Therefore, IBM introduced the cleaner "Set 3" set of codes, also with some more capabilities. Some IBM keyboards are able to switch between different code sets on command from the host. [1]

The Set 3 did however not catch on outside IBM and was used almost only for terminal keyboards.

Notes

  1. 1.0 1.1 1.2 ErrorRollOver, POSTFail and ErrorUndefined are status codes, not physical keys.
  2. 2.0 2.1 Some versions of Linux are known to exhibit bugs if a report contains 'Keyboard Int # and ~' (0x32) or 'Keyboard Clear'(0x9a)
  3. The 'Keyboard Application' key is configurable under Unix/Linux, with different defaults in different desktop environments. Sun Type 6 and Sun Type 7's Compose key sends this code.
  4. According to the spec, 'Keyboard Power' is only a status code, not a physical key.
  5. 5.0 5.1 5.2 Some of Microsoft's own keyboards send Keypad =, Keypad ( and Keypad ) on a separate "Generic HID" interface, not on the main "Keyboard" interface. Those are not supported by MS Windows itself but require a special driver.
  6. 6.0 6.1 6.2 6.3 6.4 6.5 6.6 Full-size USB keyboards from Apple have additional function keys that the more compact keyboards lack. The Apple Pro Keyboard introduced F13..F15. The full-sized Apple Aluminium Keyboard introduced F16 to F19 above the numeric keypad. Those are seldom used by Mac apps, and can be mapped to specific functions in MacOS. F14 and F15 come mapped to brightness controls in some versions of MacOS, but that can be changed.
  7. 7.00 7.01 7.02 7.03 7.04 7.05 7.06 7.07 7.08 7.09 7.10 The named function keys on Sun Type 6 and Sun Type 7 keyboards. Mapping from Kenti.net.
  8. 8.0 8.1 8.2 Media keys in top/right corner on Sun Type 6 and Sun Type 7
  9. Brazilian layout uses this key for thousands-separator. The 'Keypad +' key and this key together occupy the same space as a vertical 'Keypad +' key does on most other PC keyboards.
  10. Usage of keys is not modified by the state of the Control, Alt, Shift or Num Lock keys
  11. 11.0 11.1 Based on OS current language settings, e.g £ for GB $ for US, (period) for US/GB decimal (comma) for Int
  12. 12.0 12.1 Meta key on Sun Type 6 and Sun Type 7. Defaults to Super in some desktop environments.

Media keys
