What step do you perform to add a shadow or outline to text?

To add a shadow or outline to text, you typically select the text you want to modify, then access the text formatting options in your software. Look for effects such as "Text Shadow" or "Outline" under the text or layer styles menu. Adjust the settings, like color, distance, and blur for shadows, or thickness and color for outlines, to achieve the desired effect. Finally, apply the changes to see the updated text.
