What action is taken to display text in three columns?

To display text in three columns within PowerPoint, the process involves utilizing the add or remove columns feature in the paragraph group. This feature allows users to adjust the layout of text within text boxes or shapes by dividing the content into multiple columns, including three columns specifically.

When you select the add or remove columns button, you can customize the number of columns according to your needs, enhancing the visual organization of the text on your slides. This is particularly useful for making information more digestible in presentations, offering a cleaner layout without crowding a single area with text.

The other options do not provide a straightforward method for creating multi-column text directly. For instance, selecting a three-column layout in slide design applies a preset format to the entire slide rather than allowing for specific control over column count for particular text boxes. Using the column format option in the home tab or typing three columns in the text box settings does not accurately describe how to achieve the desired multi-column formatting either. The specific action of using the add or remove columns button is therefore the correct method to obtain text in three columns effectively.
