1 <h1 id="key">Manifest - Key</h1>
4 This value can be used to control
5 the unique ID of an extension, app, or theme when
6 it is loaded during development.
10 <b>Note:</b> You don't usually need to
11 use this value. Instead, write your
12 code so that the key value doesn't matter
13 by using <a href="http://developer.chrome.com/extensions/overview.html#relative-urls">relative paths</a>
14 and <a href="http://developer.chrome.com/extensions/extension.html#method-getURL">extension.getURL</a>.
18 To get a suitable key value, first
19 install your extension from a <code>.crx</code> file
21 <a href="https://chrome.google.com/webstore/developer/dashboard">upload your extension</a>
22 or <a href="http://developer.chrome.com/extensions/packaging.html">package it manually</a>).
24 <a href="http://www.chromium.org/user-experience/user-data-directory">user
25 data directory</a>, look in the file
26 <code>Default/Extensions/<em><extensionId></em>/<em><versionString></em>/manifest.json</code>.
27 You will see the key value filled in there.
