When you create a Web Part Request you must define captions for the text in your Web Part that is not stored as application data. Examples of such texts are the headline of the Web Part, the names of the tabs and the text in the actions.
When you create an action that will show in a Web Part you must define a caption for the action. The caption will show as a link or on a button in the Web Part depending on what HTML layout you have defined for your action.
