<h2 id="h2_key-value-tables"><span class="secno">1. </span>Keyboard Event <code>key</code> Value Tables</h2>

		<p>This section defines a list of <code>key</code> values which implementations <em class="rfc2119" title="MUST">MUST</em> support, at a minimum, in addition to support for the full range of Unicode [<a href="#references-Unicode">Unicode</a>]
			codepoints.
			The <a href="http://www.w3.org/TR/DOM-Level-3-Events/#widl-KeyboardEvent-key"><code>KeyboardEvent.key</code></a> attribute of an event <em class="rfc2119" title="MUST">MUST</em> always contain one of these control key
			or character values (even if the value is <a href="#key-Unidentified"><code class="key">'Unidentified'</code></a>). If the key represents one of the set of printable
			control characters which has a Unicode character entry, such as the tab key, the <a href="http://www.w3.org/TR/DOM-Level-3-Events/#widl-KeyboardEvent-key"><code>KeyboardEvent.key</code></a> attribute
			<em class="rfc2119" title="MUST">MUST</em> have the key value (e.g., <a href="#key-Tab"><code class="key">'Tab'</code></a>).</p>

		<p>Implementations that are unable to identify a key <em class="rfc2119" title="MUST">MUST</em> use the key value <a href="#key-Unidentified"><code class="key">'Unidentified'</code></a>.</p>

		<p class="warning"><strong>Warning!</strong> Conforming implementations <em class="rfc2119" title="MUST">MUST</em> only use <a href="#key-Unidentified"><code class="key">'Unidentified'</code></a>
			as a key value when there is no way for the implementation to detect the key value.
			Exposing only this value <em class="rfc2119" title="MUST NOT">MUST NOT</em> indicate a conforming implementation.</p>

		<p>The <a class="def" href="http://www.w3.org/TR/DOM-Level-3-Events/#glossary-key-value">key values</a> defined in this specification are based in part on the sets of keycodes from
			the <code>java.awt.event.KeyEvent</code> interface of the Java Platform, Standard Edition 6 API Specification
				[<cite><a class="informative" href="#references-KeyEvent">KeyEvent for Java</a></cite>],
			and the <code>System.Windows.Forms.Keys</code> key enumeration of the Microsoft .NET Framework 4.0 Class Library
				[<cite><a class="informative" href="#references-Keys">Keys enumeration for .Net</a></cite>].
			</p>

		<div class="note"><div class="note-title" id="h_note_1"><span>Note</span></div><p class=""><strong>Note:</strong> The keys on the numeric keypad (e.g., the keypad <code>'1'</code> key) do not generate distinct <code>key</code> values
			from their non-keypad counterparts (e.g., the <code>'1'</code> key in the main part of the keyboard).
			The <a href="http://www.w3.org/TR/DOM-Level-3-Events/#widl-KeyboardEvent-location"><code>KeyboardEvent.location</code></a> attribute can be used to determine if a key originated from the numeric keypad.</p></div>

		<div class="note"><div class="note-title" id="h_note_2"><span>Note</span></div><div class="">
			<p><strong>Note:</strong> There are special internationalization considerations for ECMAScript escaped characters.  CharMod conformance [<cite><a class="normative" href="#references-charmod">CharMod</a></cite>] <a href="http://www.w3.org/TR/charmod/#C045">expects</a> the use of code points rather than surrogate pairs in escapes.
				ECMAScript escaped characters use surrogate pairs for characters outside the Basic Multilingual Plane (<code class="char">&quot;\uD84E\uDDC2&quot;</code> for <code class="glyph">'𣧂'</code>,
				a Chinese character meaning <q>untidy</q>), rather than C-style fixed-length characters (<code class="char">&quot;\U000239c2&quot;</code> for <code class="glyph">'𣧂'</code>) or delimited escapes
				such as Numeric Character References (<code>&quot;&amp;#x239C2;&quot;</code>). Characters escaped in this manner:</p>

			<ul>
				<li>are based on UTF-16 encoding, in that it uses surrogate pairs for values outside the Basic Multilingual Plane</li>
				<li>are expressed using surrogate pairs, which makes it difficult for a human to look up the value, and might require unnecessary overhead for machine processing
					— this can also cause problems with software written in the incorrect belief that Unicode is a 16-bit character set</li>
				<li>are problematic for characters on supplementary planes (emoji, or Chinese characters on plane 2), some of which are expected to be input using a keyboard</li>
				<li>are not be suitable for Java or C, which use different escaping mechanisms (could be solved with a normalizing method)</li>
			</ul>
		</div></div>

		<p>The following sub-sections contain the normative list of case-sensitive key values, their character values (where applicable), an informative description of typical usage,
			and an informative categorization.  A conforming implementation of the <a href="http://www.w3.org/TR/DOM-Level-3-Events/#interface-KeyboardEvent">KeyboardEvent</a> interface <em class="rfc2119" title="MUST">MUST</em> support at least this set
			of values for use in the <a href="http://www.w3.org/TR/DOM-Level-3-Events/#widl-KeyboardEvent-key"><code>KeyboardEvent.key</code></a>
			attributes, though not all values <em class="rfc2119" title="MAY">MAY</em> be available on all platforms or devices.</p>
		
		<p>Future versions of this specification <em class="rfc2119" title="MAY">MAY</em> include key values not included here, which have become common since the publication of this specification.</p>
