">extension.getURL</a>. |

ension</a> |
| 22 or <a href="http://developer.chrome.com/extensions/packaging.html">package it ma

| 23 Then, in your |
| 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><

| 27 You will see the key value filled in there. |
