In the Actions Panel, use the fly-out menu to select Button Mode to view your actions as buttons (clicking the button runs the action). If you’re working with several actions in a production environment, you might want to rearrange the panel so that it fits horizontally along the bottom of your screen, making more actions accessible without scrolling. 
Note: Use the fly-out menu on the Actions Panel to toggle Button mode off in order to create new actions and/or make changes to existing actions.
