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 | |
20 (you may need to | |
21 <a href="https://chrome.google.com/webstore/developer/dashboard">upload your ext
ension</a> | |
22 or <a href="http://developer.chrome.com/extensions/packaging.html">package it ma
nually</a>). | |
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><
/em>/manifest.json</code>. | |
27 You will see the key value filled in there. | |
