Resolving a namespace using the keyboard

When writing code in .NET, if you use some function in a namespace that has not been included in your page, you get a tooltip-like popup [e.g. `System.Data.Sql`?]. If you click it, it adds the namespace to your page. Is there a keyboard shortcut to add the namespace? (I know you can use the right-click button on the keyboard, go to Resolve menu item, and select `using System.Data.Sql` ... I'm hoping for something easier). EDIT: I understand Ctrl + . also works, but you have to be on the specific command in code.
