Les tableaux ci-dessous énumèrent les valeurs clés standard dans différentes catégories de clés, avec une explication de l'utilisation habituelle de la clé. Les codes de clés virtuels correspondants pour les plateformes communes sont inclus lorsqu'ils sont disponibles.

Apprenez à utiliser ces valeurs clés en JavaScript en utilisant [KeyboardEvent.key](/fr/docs/Web/API/KeyboardEvent/key)

## 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 <kbd>Shift</kbd> and <kbd>Control</kbd> keys, and lock keys such as <kbd>Caps Lock</kbd> and <kbd>NumLock</kbd>.

\[1] In Internet Explorer (tested on release 9 and 11), as well as in all versions of Firefox, the <kbd>Windows</kbd> key is reported as `"OS"` instead of as `"Meta"`. This will be changed in Firefox per {{bug(1232918)}}. Until that's fixed, these keys are returned as `"OS"` by Firefox: `VK_LWIN` (0x5B) and `VK_RWIN` (0x5C) on Windows, and `GDK_KEY_Super_L (0xFFEB)`, `GDK_KEY_Super_R (0xFFEC)`, `GDK_KEY_Hyper_L (0xFFED)`, and `GDK_KEY_Hyper_R (0xFFEE)` on Linux.

\[2] Internet Explorer (tested on release 9 and 11) reports `"Scroll"` instead of `"ScrollLock"` for the <kbd>Scroll Lock</kbd> key.

\[3] Firefox did not add support for the <kbd>Symbol</kbd> key until Firefox 37.

\[4] Firefox generates the key value `"OS`" for the <kbd>Super</kbd> and <kbd>Hyper</kbd> keys, instead of `"Super"` and `"Hyper"`.

\[5] Chrome 67 and Firefox 63 now correctly interpret the right <kbd>Alt</kbd> key for keyboard layouts which map that key to <kbd>AltGr</kbd>. See Firefox bug {{bug(900750)}} and [Chrome bug 25503](https://bugs.chromium.org/p/chromium/issues/detail?id=25503) for further details.

\[1] On keyboards without a dedicated <kbd>Del</kbd> key, the Mac generates the `"Delete"` value when <kbd>Fn</kbd> is pressed in tandem with <kbd>Delete</kbd> (which is <kbd>Backspace</kbd> on other platforms).

\[2] Internet Explorer (tested on release 9 and 11) and Firefox 36 and earlier use "Del" instead of "Delete" for the <kbd>Del</kbd> key.

\[3] Internet Explorer (tested on release 9 and 11) and Firefox 36 and earlier generate the value `"Crsel"` instead of `"CrSel"` when the <kbd>CrSel</kbd> key is pressed.

\[1] In Google Chrome 52, the <kbd>Cancel</kbd> key incorrectly returns the key code `"Pause"`. This is fixed in Chrome 53. See [Chrome bug 612749](https://bugs.chromium.org/p/chromium/issues/detail?id=612749) for details.

\[2] In Internet Explorer (tested on release 9 and 11) and Firefox 36 and earlier, the <kbd>Esc</kbd> key returns `"Esc"` instead of `"Escape"`.

\[3] Internet Explorer (tested on release 9 and 11) and Firefox 36 and earlier report `"Apps"` instead of `"ContextMenu"` for the context menu key.

\[4] The <kbd>Attn</kbd> key generates the key code `"Unidentified"` on Internet Explorer (tested on release 9 and 11). Firefox and Google Chrome report the same, unless the Japanese keyboard layout is in effect, in which case it generates `"KanaMode"` instead.

\[5] The <kbd>Finish</kbd> key gemerates the key code `"Unidentified"` on Internet Explorer (tested on release 9 and 11). Firefox reports the same, unless the Japanese keyboard layout is in effect, in which case it generates `"Katakana"` instead.

\[6] Firefox didn't support the `"ZoomIn"` and `"ZoomOut"` keys until Firefox 37.

\[1] The <kbd>Standby</kbd> key is not supported by Internet Explorer (tested on release 9 and 11) and Firefox 36 and earlier, so it is reported as `"Unidentified"`.

\[2] Prior to Firefox 37, this key generated the value `"Unidentified"`.

## 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.

\[1] On the _X Window System_, the <kbd>Compose</kbd> key is called the <kbd>Multi</kbd> key.

\[2] The <kbd>NonConvert</kbd> 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.

\[3] The <kbd>Process</kbd> key currently returns `"Unidentified"` in Firefox and Internet Explorer. Google Chrome returns the value of the key as if IME were not in use.

\[4] Prior to Firefox 37, these keys were `"Unidentified"`.

\[5] Firefox generates the key value `"AltGraph"` instead of `"ModeChange"`.

### Korean keyboards only

These keys are only available on Korean keyboards. There are other keys defined by various platforms for Korean keyboards, but these are the most common and are the ones identified by the UI Events specification.

\[1] Prior to Firefox 37, the <kbd>Eisu</kbd> 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 <kbd>Hankaku</kbd> (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 <kbd>Zenkaku</kbd> 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 <kbd>Romaji</kbd> 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**; these 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  {{domxref("KeyboardEvent")}}'s associated {{event("compositionupdate")}} event's  {{domxref("CompositionEvent.data", "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 {{domxref("CompositionEvent.data", "data")}} will be one of the following:

## Function keys

While various platforms support different numbers of the general-purpose function keys, such as <kbd>F1</kbd>-<kbd>F12</kbd> (or <kbd>F1</kbd>-<kbd>F10</kbd>, or <kbd>F1</kbd>-<kbd>F15</kbd>, or...), 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 form a number of consumer electronics technical specifications:

- [DTV Application Software Environment](http://atsc.org/standard/a100-dtv-application-software-environment-level-1-dase-1/) (part of the {{interwiki("wikipedia", "ATSC")}} specification)
- [Open Cable Application Platform 1.1.3](http://www.cablelabs.com/specifications/OC-SP-OCAP1.1.3-100603.pdf)
- [ANSI/CEA-2014-B](http://www.ce.org/Standards/Standard-Listings/R7-Home-Network-Committee/CEA-2014-B-(ANSI%29.aspx): Web-based Protocol and Framework for Remote User Interface on UPnP™ Networks and the Internet
- [Android KeyEvent key code values](http://developer.android.com/reference/android/view/KeyEvent.html)

> **Note :** Remote controls typically include keys whose values are already defined elsewhere, such as under {{anch("Multimedia keys")}} or {{anch("Audio control keys")}}. Those keys' values will match what's documented in those tables.

## Numeric keypad keys

These keys are found on the keyboard's numeric keypad. However, not all are present on every keyboard. Although typical numeric keypads have numeric keys from <kbd>0</kbd> to <kbd>9</kbd> (encoded as `"0"` through `"9"`), some multimedia keyboards include additional number keys for higher numbers.

> **Note :** The <kbd>10</kbd> key, if present, generates events with the `key` value of `"0"`.
