macOS High Sierra
Create a workflow using selected files
If you create a lot of workflows, you can set your keyboard preferences to let you quickly create a workflow from selected files by using the shortcut menu.
To create workflows this way, you first need to add a command to the Finder shortcut menu using Keyboard preferences.
Choose Apple menu > System Preferences, click Keyboard, then click Shortcuts.
In the first column, click Services.
In the right pane under Development, select Create Workflow.
In the Finder, select the files you want to use in your workflow.
Hold down the Control key, click one of the selected files to show the shortcut menu, then choose Automator > Create Workflow.
A new workflow is created in Automator, and the selected files are specified in the first action.
