Like most other browsers, Google Chrome can be fine-tuned by typing "about:command" to show information about version number, memory usage, cached files, plug-ins and more details. Here's the full list:

about:cache - A list of all the web pages cached by Google Chrome about:dns - Prefetching DNS records produced benefits about:histograms - A list of histograms for Google Chrome's internal metrics about:internets － Google Chrome's humorous Easter egg about:memory - Measuring memory usage in a multi-process browser about:network - Used for I/O tracking about:plugins - The list of plug-ins that are available in Google Chrome about:stats - A list of internal counters and timers about:version - Shows the version number the browser, WebKit and JavaScript V8 engine view-cache:[URL] - Shows you some under-the-hood cache details view-source:[URL] - Shows the source code.

Here are some about: page screehshots from my Windows Vista:

1. Google Chrome Page - about:cache

Shows A list of all the web pages cached by Google Chrome.

Google Chrome Page - about:dns

Google Chrome prefetches the DNS records for 10 frequently visited hostnames. This feature can be disabled in Options > Under the Hood by unchecking "Use DNS pre-fetching to improve page load performance".

Google Chrome Page - about:histograms

A list of histograms for Google Chrome's internal metrics

Google Chrome Page - about:internets

This is a Google Chrome's Easter egg. It embeds the 3D Pipes screensaver from Windows, so you'll see it only if you have the file sspipes.scr in C:WindowsSystem32.

Google Chrome Page - about:memory

Summary of memory used by currently active browsers and details of memory usage of each of Chrome's processes.

Google Chrome Page - about:network

This page could be used for I/O tracking and it's a partial replacement for the Live HTTP Headers extension. Click on "Start I/O tracking", open a web page in a new tab and you'll get a list of all the images, scripts and objects loaded from that web page.

Google Chrome Page - about:plugins

The list of plug-ins that are available in Google Chrome

Google Chrome Page - about:stats

A list of internal counters and timers that has a funny subtitle "Shhh! This page is secret!".

Google Chrome Page - about:version

This page shows the version number of Google Chrome, WebKit and JavaScript V8 engine. You can also find the user-agent used by Google Chrome:

Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13

Google Chrome Page - view-cache:[URL]
