Which shortcut used for insert new slide?

In presentation software such as Microsoft PowerPoint, Ctrl+M is the correct and widely used keyboard shortcut for inserting a new, blank slide into your existing presentation. This action efficiently adds a new slide, maintaining the current presentation's design and theme, allowing users to continue building their content without interrupting their workflow. It's a productivity-boosting shortcut for anyone working with slide decks.

• Ctrl+N: This shortcut is generally used to create a new, entirely blank document or presentation file. It initiates a new project window, rather than adding a slide to an open one.
• Ctrl+S: This is the universal shortcut for saving the current document or file. It commits changes to storage but does not introduce new content like a slide.
• Ctrl+I: This shortcut is commonly used to apply italic formatting to selected text. It is a text manipulation command and has no function related to inserting new slides.
