New slides can easily be added to a presentation by clicking the bottom half of the New Slide button in the Slides group of the Home tab. If the top half of the New Slide button is clicked, the default slide layout (Title and Content) will be inserted into the presentation. By clicking the bottom half of the button, a gallery of several different slide layouts will appear.
The type of content the user intends to add will dictate which slide layout is selected. Most slide layouts include one or more placeholder to guide the user where to add content. Placeholders can contain different types of content, including text, graphics, tables, charts, and videos. Placeholders can be resized, reformatted or deleted. The most common slide layout (Title and Content) has two placeholders. The user simply needs to place the cursor inside the placeholder and begin typing to add text, or click an icon to add an object. PowerPoint automatically sizes the text as it is typed to fit within the placeholder.
The AutoFit icon is displayed next to a placeholder when more text than can fit is typed.
The alignment, font, size, and other formats can be applied to the selected text in a placeholder by using the Mini toolbar or the Home tab. A layout can be changed by clicking the Layout button to the right of the New Slide button, and choose a different layout. To delete a slide, right-click the slide in the thumbnail pane, and choose Delete Slide from the shortcut menu.
