The Symbol Sprayer acts like a particle sprayer—letting you add a large number of identical objects to the artboard at one time. For example, use the symbol sprayer to add hundreds of grass blades, wildflowers, bees, or snowflakes.
To add symbol instances, click or drag where you want the new instances to appear.
To delete symbol instances, hold down Alt (Windows) or Option (Mac OS) as you click or drag where you want to remove instances.
