<p>
多功能地址栏API允许您在Google Chrome浏览器的地址栏（又叫多功能地址栏）中注册一个关键字。
</p>
<p>
<img src="stable/static/images/omnibox.png" width="300" height="150"
alt="A screenshot showing suggestions related to the keyword 'Chromium Search'" />
</p>
<p>
当用户输入您的扩展程序的关键字时，用户开始完全与您的扩展程序交互。每一次按键消息都将发送至您的扩展程序，您可以作出回应，提供建议。
</p>
<p>
建议可以具有各种不同格式。当用户接受某个建议时，将通知您的扩展程序作出反应。
</p>
<h2 id="manifest">Manifest</h2>
<p>
您必须在<a href="manifest.html">清单文件</a>中包含<code>omnibox</code> <code>keyword</code>
属性来使用多功能地址栏API，您还应该指定一个16×16像素的图标，当用户进入关键字模式时，显示在地址栏中。
</p>
<p>
例如：
</p>
<pre>{
"name": "Aaron的多功能地址栏扩展",
"version": "1.0",
<b>"omnibox": { "keyword" : "aaron" },</b>
<b>"icons": {</b>
<b>"16": "16-full-color.png"</b>
<b>},</b>
"background": {
"persistent": false,
"scripts": ["background.js"]
}
}</pre>
<p class="note">
<strong>注意:</strong>
Chrome浏览器会自动创建您的16×16像素图标的灰度版本。您应该提供彩色的图标，以便用于其它需要颜色的情况，例如，
<a href="contextMenus.html">右键菜单API</a>也使用16×16像素的图标，但是显示为彩色。
</p>
<h2 id="examples">例子</h2>
<p>
您可以在
<a href="samples.html#omnibox">示例页面</a>找到这一API的例子。
