Use the Toolbar to Work with Comments
You can use the markup toolbar to work with comments in the Conversations tab. The toolbar provides commonly used formatting actions so that you don't have to remember or search for the right markup language syntax you need (whether Textile, Confluence, or Markdown). The toolbar also provides options to customize the content editor itself, so you can toggle line numbers on and off, change line wrapping, and show (or hide) the content editor's minimap.
