How do you initiate the footer setup for every slide?

Initiating the footer setup for every slide in PowerPoint is accomplished by navigating to the Insert tab and selecting the Header & Footer option. This action opens a dialog box where you can choose to add footers to the slides, including text for the footer itself, date, and slide numbers.

Using the Insert tab is the correct approach because it is specifically designed for adding components to slides, including elements like headers, footers, text boxes, images, and other objects. This feature allows for uniformity and consistency across your presentation, making it easy to display relevant information at the bottom of each slide.

In contrast, accessing the slide design tab does not offer footer configuration capabilities, and the review tab is primarily used for editing and reviewing changes rather than adding slide content. Additionally, the option related to adding notes pertains to speaker notes rather than footer elements on the slides.
