1. ACTIONS PALETTE
Make sure that your actions palette is activated and visible. It typically shows up as a tab on the history palette, but this may vary depending on your workspace.
If your actions palette is nowhere to be found, you can activate it under the “Window” menu. Once you do this, you should see a palette similar to the one in this photo. If you don’t have any actions defined yet, you’ll probably just see the “Default Actions” set.
