Gmail, Now With Added Magic! Embedded Google Web Search

Go into your Gmail account, click on the Google Labs icon, and enable Google Search in your Gmail account.

A simple little search box will appear right there in your sidebar. But that's not even the awesome part. The range of tricks you can play with the search results is astounding.

You can click a drop-down menu next to the result and start to really have fun.

If you're viewing an email, the drop-down menu offers to let you reply with the result. If you're writing a new email, you can choose to paste the URL, paste the result, or send the whole thing in an email. And if you're using Google Talk, the menu further allows you to send the result and URL via chat to any of the people with whom you may be chatting.

So, you no longer have to toggle between your favorite email and your favorite search engine.
