After editing the document, we sometimes may want to insert a blank page in the middle to supplement related content. So how can we do that?

After clicking the page, click the Blank Page drop-down button in the Insert tab. Here, we can choose Vertical Text Box or Horizontal Text Box.

If we want to delete a blank page, place the mouse on the blank page. Now hold down the Backspace key, and press the Delete key to delete the blank page.

This skill could be compatible with Microsoft Office PowerPoint.
