What is the correct way to add a new slide to a presentation?

Adding a new slide to a presentation is most commonly done by clicking "New Slide" in the Home tab of the PowerPoint interface. This action directs PowerPoint to insert a blank slide into the presentation at the location of your current selection in the slide sorter. The Home tab is specifically designed for tasks relevant to managing slides, including adding new ones, which makes this method straightforward and intuitive for users.

The "New Slide" option typically allows users to choose various layouts for their new slide, contributing to a more organized and aesthetically pleasing presentation structure. It streamlines the process of enhancing a presentation by ensuring that new content can be seamlessly integrated.

Other methods, like selecting a slide type and clicking "Add" or using the "Edit" menu, may not be standard practices in the current interface of PowerPoint, particularly as functionality evolves. Additionally, simply double-clicking the slide thumbnail area does not initiate the action of adding a new slide; rather, it may lead to editing an existing slide or produce inconsistent results depending on the context.
