What should you do after selecting an audio file to insert it?

After choosing an audio file to insert into a PowerPoint slide, the appropriate action is to click the Insert button, which actually incorporates the selected audio file onto the slide. This method ensures that the audio is properly integrated and that all necessary formatting settings are applied automatically by PowerPoint.

Using the Insert button activates the command that allows the software to load the file and prepare it for use within the presentation. Clicking Open will only confirm the selection and may not directly add the audio file to the slide. Pressing Enter typically does not execute the Insert function in this context, as it is a general command that could lead to unintended results. Similarly, right-clicking and choosing Insert might not always show an option to directly insert an audio file, depending on the interface and context. Thus, utilizing the Insert button is the most effective and reliable method to ensure the audio file is successfully included in the presentation.
