clipped from: www.visual-blast.com An action is a series of tasks that you play back on a single file or a batch of files - menu commands, palette options, tool actions, and so on. You can create an action that changes the size of an image, applies a filter to the image for a particular effect, and then saves the file in the desired format. Nice, isn’t it !
Actions can include stops that let you perform tasks that cannot be recorded (for example, using a painting tool).
Photoshop and Illustrator come with predefined actions installed that help you perform common tasks. You can use these actions as is, customize them to meet your needs, or create new actions. Actions are stored in sets to help you organize them.
You can record, edit, customize, and batch-process actions, and you can manage groups of actions by working with action sets.
