The Microsoft Office Labs team have now launched their own web site/community at www.officelabs.com. This is a site dedicated to “Concept testing”. This means that we can expect to see some nice productivity enhancements to the Office family and get a chance to take them for a test-drive. 
The aim of the site is for the Office Labs team to gather information from their “tools” and evaluate the usage of them and get a discussion started. So when you download and install the tools from Officelabs.com then make sure to participate in the Usage Metrics.
First of all the long anticipated Search Commands is now available. Search Commands is an addition to the Office 2007 ribbon and contains a search function for commands. Just enter the command you would like to find and use it through the result.
This is a great add-on and should be valuable for all new Office 2007 users.
