Studies show that a specific structure of a post can make it easier to understand and memorize the content. Lists fit this use case almost perfectly and can help you add structure to the information inside your post.
Any paragraph or several of them can be converted into a list.
To do so:
1) click on the paragraph you wish to convert or select several by holding cmd key (if you are using Mac) or Ctrl key (if you are using Windows).
2) click on the "Convert to list" icon in your right toolbar.
You can also switch between two types of lists - numbered and unnumbered via the list type selector in the top toolbar.
To convert the list back to a paragraph you can either press "Convert to list" button again, while the list is still in focus or open contextual menu with the right-click of your mouse and pick a "Convert list to paragraphs" option.
