I like using Dave's Quick Search Toolbar. Have had it for almost two years now, and I am extremely happy with it.http://www.dqsd.net/
Dave's Quick Search Deskbar is a tiny textbox that Dave Bau designed for search hounds with weary mouse-fingers. Unlike the Google Toolbar, this little deskbar lets you launch searches without starting a web browser first, directly from your Windows Explorer Taskbar.
You type your search and hit Enter for a regular Google search.
If you're feeling lucky, tack an exclamation point on to the end of your search - "pow! " - and go directly to the top ranked hit. It is Powered By Google, and Yes it Really Works.
Now you can do searches no matter what you are doing - email, word processing, programming, whatever.
There's more. You're not a captive to Google. Do Yahoo searches with a "yh question", get Merriam-Webster definitions with a "colon:", get Bloomberg stock quotes like this "msft intc csco$", and find Switchboard phone numbers by saying "Lois Lane#". You can search real "news." search "newsgroups," check "weather*", or "comparison shop$$". There's a built in calculator when you need to know "pow(1.0625, 30) " is 6.1640785. And so on.
Too much to remember? Click the button on the search bar or press F1 and a menu shows you all your choices. Not enough space on your deskbar? It includes a clock so that you can free up some space by turning off the system deskbar clock.
Missing a feature you need? If you know HTML and want to add your own functionality, you can - it is distributed under GPL and is available at SourceForge .
It'll make you super-quick.
You'll be ready to take on the world and surf like never before.
