One of my favorite features of Google Chrome is “tab to search”: a feature that offers you the ability to search a site before even going to its home page:
For an example of this, you can check out http://tomshardware.com
This feature is extremely easy to implement in SharePoint!
- Create an XML “OpenSearchDescription” file, and store it in the style library.
- Write a link to the XML definition file in your master page.

Update: It should probably be noted that there is a broken feature in the SharePoint 2010 basic search center which attempts & fails to inject a similar open search description using a file called /_layouts/srchconnectorgenerator.aspx. I’ve not seen this actually work (it throws up a correlation ID which I haven’t the time to investigate), and it doesn’t provide a link on the root site, so it’s unlikely to be picked up by Chrome.
Should also note that this affects a similar (but less used and less useful) option in Firefox, and versions of IE below IE9:
