Google Chrome - Disable Network Connection

Using Google Chrome, is it possible to "Work Offline", that is, disable the network connection. I'm looking for the same feature that is included in Firefox 4.x under the File menu called Work Offline. This feature will assist in testing a HTML 5 cache manifest.

Unfortunately, it's not. Some Google services will work online (Gmail for one), but that doesn't exactly help you. You can open a local file with Ctrl-O but again, this doesn't really help you.

At least with 47.0.2526.80, Chrome Developer tools have a Network Throttling preset option Offline.
