VS2010 Intellisense: navigate signatures w/ keyboard?

new XmlSerializer().

I typed the code above, and an Intellisense menu appears. One of the opt开发者_如何学Cions in the menu is the Serialize method. I navigate to that using my keyboard.

Once Serialize is selected, a submenu appears to the right of the main Intellisense menu, showing several signatures for the Serialize method.

How can I navigate this signatures submenu without using my mouse? How can I look through these signatures using my keyboard?

I've just tried using the up and down arrows on my keyboard and it seems to do the trick just fine.
