As is typical for Google, its new Chrome browser features a tabula rasa interface, without the Windows menu system and toolbars that many browser users are used to. At the same time, it shares much code with Mozilla's Firefox browser, and is customizable in many of the same ways as Firefox. Around the web, I'm already seeing some astute tutorials and resources show up for those interested in souping Chrome up and getting the most out of it. Here are some strong resources.
Lifehacker has done a nice power user's guide to using Chrome. You'll find keyboard shortcuts, customization options and more, including ways to make the interface a little less tabula rasa than it is by default, if you care to.
The Google Operating System blog has done a nice collection of tips on Chrome, ranging from how to undo a closed tab to how to monitor the resources being used by any given web page. Find their general tips here. Did you know you can do calculations like the one at left right from the address bar?
Chrome is based on some of the same code as Mozilla's Firefox, and just as you can use the about: command in Firefox's address bar to pull up lots of configuration and other options, Chrome allows you to work with such commands to. For example, type about:plugins in Chrome's address bar to find out what plugins are available. The Google Operating System blog also has a good collection of tips on how to use these commands for Chrome, found here.
Chromium is the open source project behind Google Chrome, and is the code from which upcoming Mac and Linux versions of Chrome are being developed from. You can join in on developer discussions on Chromium, report bugs, submit patches and otherwise participate here.
If you're interested in how the Linux version of Chrome is coming along, or want to get involved, there is now a development status page. Or check in on the Chromium Developer technical page.
