Contents is a sidebar that displays a numbered, indented outline of document headings, with a selectable number of heading levels. Clicking a heading jumps to that location in the document. When moving to a heading, the heading will be positioned at the top of the screen. If a heading is in color, the sidebar will display it in that color. If headings have been modified, added, or deleted, the sidebar can be refreshed by clicking the Refresh button, or will automatically refresh the next time a heading is clicked.
