UPDATE: If it still feels like too much typing to find the information on the MSDN site, check out this little IE toolbar gadget by Nick Parker. Nothing fancy, but it will take you right to your namespace.
Just to make it easy to find the documetation you need, the brainiacs at MSDN are using a thing called URL Aliases. The gist of what it accomplishes is shown here with this tip:
Tip: Our system supports URLs of the format http://msdn2.microsoft.com/library/.aspx.
For example: http://msdn2.microsoft.com/library/system.xml.serialization.aspx, so navigating to API reference pages will be quicker and easier.
This will make finding documentation much quicker to find. Kudos!
