Have you tried new google toolbar?
It is really great tool with full customization and support. You can add Search Buttons of your choice. Like I recently have installed Overture Suggestion Keyword Tool Search Button. Now after writing main keyword in main search box of the toolbar, just click the OTK button and wow, it is fetching results from Overture.
Another feature I liked much is the capability to transfer any opened page to gmail a/c, or blogger a/c. Amazingly you can bookmark a webpage and can access your bookmarks from anywhere, i mean from any computer!
If you not already updated your toolbar i suggest you do this now. It is real time saver when online.
