Presentation software like Microsoft PowerPoint provides shortcut keys to make creating slides faster and easier.
Pressing Ctrl + M will instantly insert a new slide below the current slide in your presentation.
This saves time compared to using the mouse and menu options every time you want to add a slide.
On the other hand, Ctrl + N is generally used to create a new file or presentation, not just a slide.
Ctrl + Alt + N and Ctrl + Alt + M are not default shortcuts for this function in most presentation tools.
Learning shortcuts like Ctrl + M helps presenters work efficiently, especially during live edits or quick changes.
Therefore, Ctrl + M is the correct shortcut to add a new slide.
