Google Chrome’s Omnibar seems to be fairly robust and useful just like Mozilla Firefox’s Awesomebar. I like that you can add search engines and keyword them just like bookmarks in Firefox.

Here are some of the ones I found useful.

gl | http://www.google.com/search?q=%s&btnI=I’m+Feeling+Lucky

That’s it so far.

Update: I don’t know when i’ll use it but i know I use it quite a bit when i watch foreign films. It allows for easy translation. You can do more
