Surfaces

In the top left corner of the Material/Color Change dialog is the Surfaces list.

Here, you click to choose which part of the component the material or color change should apply to. For example, on one of Configura Standard's office desks, you can change the table top, leg, and panel:

Each surface has an icon that tells you whether it is visible in 2D, 3D, or both:

Selecting a surface in the list will highlight the material/color currently in use in the overview:

Note:

To select multiple surfaces in the list, hold down the Ctrl key and click the surfaces you want to select. Holding down the Shift key while clicking the first and the last surface in the list will select all surfaces.
You may experience that the overview is flickering a little when you click different surfaces. It is simply because it adjusts the tabs and the material categories to show you which material or color is on the surface that you have selected.
