<!--OddPage-->
<h2 id="h2_keyboard-layout"><span class="secno">1. </span>Keyboard Layout</h2>
		<p><em>This section is informative</em></p>

		<p>Alphanumeric keyboards are the most common way for users to generate keyboard events.
			This section provides an overview of standard keyboards and their physical layouts.
			</p>

		<div id="keyboard-common-layouts" class="section">
			<h3 id="h3_keyboard-common-layouts"><span class="secno">1.1 </span>Standard Keyboard Layouts</h3>

			<p>This section describes the physical layouts found on commonly available keyboards.
				</p>

			<div id="keyboard-sections" class="section">
				<h4 id="h4_keyboard-sections"><span class="secno">1.1.1 </span>Keyboard Sections</h4>
			
				<p>When discussing keyboard layouts, it is convenient to divide the standard keyboard into distinct sections
					and to label each row.
					</p>

				<div id="figure-keyboard-sections" class="figure">
					<img src="images/keyboard-sections.svg" width="684" height="225" alt="The five general sections of a standard keyboard" />
					<div class="figcaption">Fig. <span class="figno">1</span> <span class="fig-title">The five general sections of a standard keyboard</span></div>
				</div>

				<p>These keyboard sections are:
					</p>

				<ul>
					<li>The <em>Alphanumeric</em> section is the main part of the keyboard and is where most of the keyboard variation occurs.
						When a user selects a keyboard layout, it is the keys in this sections that are most affected.
						</li>
					<li>The <em>Control Pad</em> and <em>Arrow Pad</em> sections contain the arrow keys and other editing keys.
						</li>
					<li>The <em>Numpad</em> (also known as the &quot;numeric keypad&quot; or &quot;number pad&quot;) contains number and math keys to make it 
						easier to enter numeric data.
						</li>
					<li>And finally, the <em>Function</em> section contains miscellaneous function keys and special keys like Escape.
						</li>
				</ul>
			
				<p>To make it easier to identify keys, the rows on the keyboard are named starting with &quot;A&quot;
					for the bottom row up to &quot;E&quot; for the top row. The row of keys in the Function section are considered
					to be in row &quot;K&quot;.
					These row names are consistent with those given in the ISO/IEC 9995-1 specification.
					</p>
				<p>Note that many keyboards (both modern and legacy) have extra keys that do not fit neatly into the above sections.
					Some of these keys are covered in the <a href="#key-media">Media Keys</a> section.
					</p>
			</div>
<!-- keyboard-sections -->


			<div id="keyboard-101"  class="section">
				<h4 id="h4_keyboard-101"><span class="secno">1.1.2 </span>Standard &quot;101&quot; Keyboard Layout</h4>
				<p>The standard &quot;101&quot; keyboard (commonly referred to as the &quot;US layout&quot;) is the only layout that uses the <code class="code">'Backslash'</code> code.
				   All the other layouts omit this key and expand the <code class="code">'Enter'</code> key to occupy
				   two-rows.
				</p>

			<p>Many keyboards contain special keys to control media functions.  Increasingly, many media devices, especially televisions, are Web-enabled.  Hybrid keyboard/remote-control

			<p>Because of the smaller form factor, keys (or buttons) on a remote control will often be modal,

				Additionally, many keys serve as toggles, to change back and forth between two or more states
				(see toggling keys).
				These remote control buttons typically do not have modifier states so each button is assigned a
				single function (like &quot;Play&quot;, &quot;Pause&quot;, &quot;Up&quot;, &quot;Menu&quot; or &quot;Exit&quot;).

				of keyboard events and values, for ease of authoring and compatibility with existing content.</p>

			<p>Chording keyboards, also know as chorded keysets or chord keyboards, are key input devices which produce values by pressing several keys in combination or sequence,
				normally to simulate a full range of characters or commands on a reduced set of keys, often for single-handed use.  A chording keyboard <em class="rfc2119" title="MAY">MAY</em> have additional mode
