To create a bulleted list in the content placeholder, which key must be pressed between each item?

To create a bulleted list in the content placeholder of PowerPoint, pressing the "Enter" key is essential between each item. When you type your first list item and then hit "Enter," PowerPoint automatically generates a new bullet point for the subsequent item, allowing you to continue your list seamlessly. This function helps users quickly and efficiently format their content into organized bullet points, making it easier for the audience to read and understand.

The other choices do not fulfill this specific action in creating a bulleted list. For example, pressing the space bar merely adds a space but does not create a new bullet point. The Tab key typically indents the bullet point further rather than starting a new one, and the Shift key is generally used for different keyboard shortcuts or functions, not for entering text items in a bulleted format.
