STOPS AND CONDITIONALS
While recording an Action you can add in Stops. These can be helpful if you need to pause the Action at certain points, perhaps to add in an explanatory note. Click the flyout menu at the top of the Actions Panel and choose Insert Stop. You can also insert Conditionals in this way. Conditionals let you send your Action off in different directions by, for example, choosing different edits depending on whether an image is vertical or horizontal. Conditionals work in combination with other Actions, so if you want to use them then you need to create further Actions for each if/or conditional scenario.
