IE7 comes with a built-in search bar on the right of the address bar.  If you pull down the right arrow, there is an option to choose where a search should occur.  I use Google mostly, so I change the default to Google.  There is also another option ” Find more Providers” which will allow you to add Ask.com (you can choose to eliminate any trace of what you searched for – which is good for looking for Christmas Gifts), or eBay, Monster, Amazon, Facebook, MySpace, Expedia, etc.  You can also add your own provider, such as “http://translate.google.com/translate?hl=en&sl=es&u=TEST“, which can be then used to bypass Internet filters in locations that have sites blocked.  Use this knowledge wisely or you might want to monitor you user’s activities to see if they are already using this trick.
