Try out ChromeOS/ChromiumOS Without Installing It

If you’ve been wanting to try out ChromeOS, the new operating system from Google, but weren’t lucky enough to get in on their free laptop giveaway, don’t worry, you can, thanks to a user named Hexxeh.  Hexxeh has taken the source code – called ChromiumOS – and builds it nightly, so you can always download the latest and greatest version of ChromiumOS, which will eventually turn into ChromeOS.
What’s better, Hexxeh has also added more hardware support to ChromiumOS than its default, “vanilla” builds (which are also available from Hexxeh), which will make it much more useful for folks not using the Cr-48 (the Chrome Notebook).

Add Bookmarks Toolbar Button to Google Chrome

By default, the only bookmarks button on the Google Chrome toolbar is a small star at the end of address bar, which allows you to add a new bookmark or favorite. There are two methods for viewing and managing your existing bookmarks.
Each method only takes a few seconds to set up and is perfect for those who do not want to open the Google Chrome settings menu each time they want to view their bookmarks.

Keyboard Shortcuts

The easiest method uses two keyboard shortcuts. If you do not see a bookmarks bar under your address bar, press Ctrl + Shift + B to view your bookmarks bar.
