Special values
Values of key which have special meanings other than identifying a specific key or character.
KeyboardEvent.key Value | Description | Virtual Keycode | |||
|---|---|---|---|---|---|
| Windows | Mac | Linux | Android | ||
"Unidentified" | The user agent wasn't able to map the event's virtual keycode to a specific key value. This can happen due to hardware or software constraints, or because of constraints around the platform on which the user agent is running. | varies | varies | varies | varies |
Modifier keys
Modifiers are special keys which are used to generate special characters or cause special actions when used in combination with other keys. Examples include the Shift and Control keys, and lock keys such as Caps Lock and NumLock.

[3] Firefox did not add support for the Symbol key until Firefox 37.
[4] Firefox generates the key value "OS" for the Super and Hyper keys, instead of "Super" and "Hyper".
[5] Chrome 67 and Firefox 63 now correctly interpret the right Alt key for keyboard layouts which map that key to AltGr. See Firefox bug bug 900750 and Chrome bug 25503 for further details.

IME and composition keys
Keys used when using an Input Method Editor (IME) to input text which can't readily be entered by simple keypresses, such as text in languages such as those which have more graphemes than there are character entry keys on the keyboard. Common examples include Chinese, Japanese, Korean, and Hindi.
Some keys are common across multiple languages, while others exist only on keyboards targeting specific languages. In addition, not all keyboards have all of these keys.

If you wish to identify which specific dead key was pressed (in cases where more than one exists), you can do so by examining the | See Dead keycodes for Linux below | |||
"FinalMode" | The Final (Final Mode) key is used on some Asian keyboards to enter final mode when using IMEs. | VK_FINAL (0x18) | |||
"GroupFirst" | Switches to the first character group on an ISO/IEC 9995 keyboard. Each key may have multiple groups of characters, each in its own column. Pressing this key instructs the device to interpret keypresses as coming from the first column on subsequent keystrokes. | GDK_KEY_ISO_First_Group (0xFE0C) | |||

[1] On the X Window System, the Compose key is called the Multi key.
[2] The NonConvert key is reported as "Nonconvert" instead of the correct "NonConvert" by Internet Explorer (tested on release 9 and 11) and Firefox versions 36 and earlier.

[4] Prior to Firefox 37, these keys were "Unidentified".
[5] Firefox generates the key value "AltGraph" instead of "ModeChange".

[1] Prior to Firefox 37, the Eisu key was mapped to "RomanCharacters" by mistake.
[2] VK_HANGUL and VK_KANA share the same numeric key value on Windows, as do VK_HANJA and VK_KANJI.
[3] Prior to Firefox 37, the Hankaku (half-width) key generated the key value "HalfWidth" on Firefox. Also, this key generates the value "Unidentified" on Internet Explorer (tested on release 9 and 11).
[4] Internet Explorer (tested on release 9 and 11) reports "Unidentified" for the Zenkaku key; Firefox 36 and earlier identify this key as "FullWidth" on Japanese keyboard layouts and "Unidentified" on all other keyboard layouts. Firefox 37 and later, and all versions of Google Chrome, correctly return "Zenkaku".
[5] "Unidentified" in Internet Explorer (tested on release 9 and 11). Firefox 36 and earlier identify the Romaji key as "RomanCharacters" on Japanese keyboards and "Unidentified" for other keyboards; this is corrected to return "Romaji" in Firefox 37 and later.
[6] This key is reported as "Unidentified" prior to Firefox 37.
Dead keycodes for Linux
Linux generates accented characters using special dead keys. Dead keys are keys which are pressed in combination with character keys to generate accented forms of those characters. You can identify which specific dead key was used (if more than one exists) by examining the KeyboardEvent's associated compositionupdate event's data property.
You can find a table of the dead keys and the characters they can be used with to generate accented or otherwise special characters on Linux using GTK.
The value of data will be one of the following:

Media controller keys
Because modern remote controls for media devices often include buttons beyond the basic controls covered elsewhere in this document, key values are defined for a broad array of these additional buttons.
The values below are derived in part form a number of consumer electronics technical specifications:
- DTV Application Software Environment (part of the ATSC specification)
- Open Cable Application Platform 1.1.3
- ANSI/CEA-2014-B: Web-based Protocol and Framework for Remote User Interface on UPnP™ Networks and the Internet
- Android KeyEvent key code values
Note: Remote controls typically include keys whose values are already defined elsewhere, such as under Multimedia keys or Audio control keys. Those keys' values will match what's documented in those tables.
