+- **unorderedListStyle**: can be `*`, `-` or `+`. Defaults to `*`.
 - **scrollbarStyle**: Chooses a scrollbar implementation. The default is "native", showing native scrollbars. The core library also provides the "null" style, which completely hides the scrollbars. Addons can implement additional scrollbar models.
 - **element**: The DOM element for the TextArea to use. Defaults to the first TextArea on the page.
 - **forceSync**: If set to `true`, force text changes made in EasyMDE to be immediately stored in original text area. Defaults to `false`.
