To paste an object that has been copied in PowerPoint, which keyboard shortcut should you use?

To paste an object that has been copied in PowerPoint, the appropriate keyboard shortcut to use is Ctrl + V. This is a universally recognized shortcut across many software applications, including PowerPoint, that allows users to insert or paste content that has been previously copied or cut to the clipboard.

When you use Ctrl + C, you are actually performing the action of copying an object, which places it in the clipboard for later use but does not paste it into your presentation. Similarly, Ctrl + A is a shortcut for selecting all objects or text in a slide, and Ctrl + S is used to save your presentation. Therefore, these options do not facilitate the act of pasting an item into your slide. Thus, knowing that Ctrl + V is specifically designated for pasting makes it the correct choice for this action in PowerPoint.
