How to Format Lists in Google Slides
Use bulleted lists when the order of items in a list doesn't matter, such as listing items you need to buy. When the sequence of items in a list does matter, such as to present step-by-step instructions, use a numbered list instead.
The text is formatted as a list.
Whether you're working with a numbered or bulleted list, you can change the style to better fit your presentation.
The menu shows several different bullet or numbering styles, as well as what they look like.
