Customize the CRM Ribbon

Ribbon used to perform actions and add custom controls.
Displays actions that are relevant to each area of the application as users access them.
Dynamics CRM provides RibbonDiffXml definitions for all ribbons in the application for you to customize.
You can access the default ribbon definitions in the SDK\SampleCode\CS\Client\Ribbon\ExportRibbonXml\ExportedRibbonXml folder - this will generate all the entities ribbons
