Revision 1106657 of KeyboardEvent.key

<p>{{APIRef("DOM Events")}}{{Draft}}</p>

<p><span class="seoSummary">The <code><strong>KeyboardEvent.key</strong></code> read-only property returns the value of a key or keys pressed by the user.</span> Its value is determined as follows:</p>

<ul>
 <li>If the pressed key has a printed representation, the returned value is a non-empty Unicode character string containing the printable representation of the key.</li>
 <li>If the pressed key is a control or special character, the returned value is one of the <a href="#Key_values">pre-defined key values</a>.</li>
 <li>If the <code>KeyboardEvent</code> represents the press of a dead key, the key value must be "<code>Dead</code>".</li>
 <li>If more than one key is pressed and the combination includes a modifier that makes the resulting keystroke non printing, the returned value is the printable character. For example, if the combination were Control + a, the letter "a" is returned.</li>
 <li>Some specialty keyboard keys (such as the extended keys for controlling media on multimedia keyboards) don't generate key codes on Windows; instead, they trigger <code>WM_APPCOMMAND</code> events. These events get mapped to DOM keyboard events, and are listed among the "Virtual key codes" for Windows, even though they aren't actually key codes.</li>
 <li>If the key cannot be identified, the returned value is <code>"Unidentified"</code>.</li>
</ul>

<h2 id="Example">Example</h2>

<p>This example uses {{domxref("EventTarget.addEventListener()")}} to listen for {{event("keydown")}} events. When they occur,&nbsp; the key's value is checked to see if it's one of the keys the code is interested in, and if it is, it gets processed in some way (possibly by steering a spacecraft, perhaps by changing the selected cell in a spreadsheet).</p>

<pre class="brush: js">
window.addEventListener("keydown", function (event) {
  if (event.defaultPrevented) {
    return; // Should do nothing if the key event was already consumed.
  }

  switch (event.key) {
    case "ArrowDown":
      // Do something for "down arrow" key press.
      break;
    case "ArrowUp":
      // Do something for "up arrow" key press.
      break;
    case "ArrowLeft":
      // Do something for "left arrow" key press.
      break;
    case "ArrowRight":
      // Do something for "right arrow" key press.
      break;
    case "Enter":
      // Do something for "enter" or "return" key press.
      break;
    case "<code>Escape</code>":
      // Do something for "esc" key press.
      break;
    default:
      return; // Quit when this doesn't handle the key event.
  }

  // Consume the event to avoid it being handled twice
  event.preventDefault();
}, true);

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

<p>[2] Internet Explorer 9 reports <code>"Scroll"</code> instead of <code>"ScrollLock"</code> for the <kbd>Scroll Lock</kbd> key.</p>

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

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

<h3 id="Function_keys">Function keys</h3>

<p>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, <code>"F24"</code> is a valid key value.</p>
