Key values for keyboard events
The tables below list the standard values for the KeyboardEvent.key property, with an explanation of what the key is typically used for. Corresponding virtual keycodes for common platforms are included where available.
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.

[1] In Firefox, the Windows key is reported as "OS" instead of as "Meta". This will be changed in Firefox per Firefox bug 1232918.

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

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.

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

[3] Prior to Firefox 37, the Hankaku (half-width) key generated the key value "HalfWidth" on Firefox.
[4] Firefox 36 and earlier identifies 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] Firefox 36 and earlier identifies 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:

Function keys
While various platforms support different numbers of the general-purpose function keys, such as F1–F12 (or F1–F10, or F1–F15, etc.), the first few are specifically defined as follows.
If more function keys are available, their names continue the pattern here by continuing to increment the numeric portion of each key's name, so that, for example, "F24" is a valid key value.

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 from a number of consumer electronics technical specifications:
- DTV Application Software Environment (part of the ATSC specification)
- Open Cable Application Platform
- 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.
