Tool groups are used to specify what palettes and popup toolbars appear for certain groups of tools.

To create a tool group, click the "+" icon.
Assign a name to the tool group.
In the top part of the window, select the toolbars that contain the tools in the group. In the lower part, select the palette (or palettes) and popup toolbars that will appear while you are working in any of these tools.

In the above example, the Selection Info palette will be the default open palette when you are working with any 3D Modify tool. Another example could be to open the Calculator palette when using any Dimension tool.
