In addition to the hundreds of actions in the Library, developers have posted many completed actions on the Internet. When you find new actions you want to use, you can import them into Automator and use them in your workflows.
Copy the action or actions you want to add to your Mac.
Choose File > Import Actions.
Locate the action, select it, then click Import.
Quit Automator, then open it again.
The new action should be available from the Library.
