Navigate the style hierarchy using the breadcrumb bar
When you are in the editing scope of a style or template in Expression Blend 2, a breadcrumb navigation bar appears at the upper left of the artboard.
The breadcrumb bar appears for any selected object that can have a custom style or template applied to it.
Select an object on the artboard or under Objects and Timeline that supports styles and templates. For example, select a button.
At the top of the artboard, select the breadcrumb button that appears.
If the object does not support styles or templates, the breadcrumb button for the object is unavailable.
From the pop-up menu that appears below the breadcrumb, select which kind of resource to create.
For information about how to create styles and templates, see Create a style resource, Create or edit a control template, and see the section on "The difference between styles and templates" in the Style and template overview.
