The wrench icon in the Google Chrome toolbar offers a menu of settings you can use to control and adjust how the browser looks and behaves. Chrome can also reveal more information on its internal pages with a series of commands typed directly into the address/search box (also known as the “omniboxâ€). While many of these commands are designed for programmers looking to debug Web-page code, some are helpful for quickly seeing what plug-ins and extensions are installed, or to see the browser's bookmarks list.
To see a list of typed commands available, click into the Chrome omnibox and type “chrome:about†(without the quotation marks or any spaces). In the list, you can click the various links to see all kinds of things about Chrome, including the downloads list, the browser history and cache, the program's memory usage and more. (These links can also be typed directly into the Chrome omnibox at any time.) The “chro me:flags†command even displays a list of hidden experimental features available, but the browser warns that you use these at your own risk since they are unofficial.
You can substitute the word “about†instead of “chrome†for the commands as well. Mozilla's Firefox browser has its own set of internal pages that can be summoned with the “about:about†command, including the playful “about:robots†page.
