Get information about actions
Each action has its own description that tells you what it does. The description may contain the action’s required input, output, and result. Although some actions require no input or output, others have very specific input requirements, such as a specific type of file from a previous action. For example, an action that requires a graphic file for input can only follow an action in the workflow that has a graphic file as output.
See the description of an action in the Library: Click the action. A description of the selected action appears in the bottom-left corner of the Automator window.
