Studies show that a specific post structure can make it easier to understand and memorize the content. Lists fit this use case perfectly and can help you to structure your content better.
You can convert any paragraph or several paragraphs into a list.
To do that:
Click on the paragraph you wish to convert or select several by holding the CMD key (if you are using Mac) or the CTRL key (if you are using Windows)
Click on the Add list button in your Side Toolbar
You can also switch between two types of lists (numbered and bullet lists) via the list type selector in the Upper Contextual Toolbar.
To convert the list back to a paragraph, you can either press the Add list button again while the list is still in focus or open the Context menu with the right-click of your mouse and pick a "Flatten list option.
