It's easy to search the Web directly from Yahoo! Mail.

In the upper-right corner of your Yahoo! Mail window you'll see a gray "Search" button. The box next to this button says "Search the Web." Click in this box and type what you're looking for. When you press Enter or click the "Search" button, a new browser window opens with your search results.

When you've found what you want, you can return to your Yahoo! Mail page—it's still open. See it? Just click it!
