How to expand and collapse paragraphs
To collapse a paragraph place your cursor on the heading, right-click and select Expand/Collapse – Collapse Heading.
This option will only be available if you have applied a heading style. Another, quicker way to collapse the paragraph is to click the little grey triangle to the left of the heading. If you want to collapse all paragraphs right-click any heading and select Expand/Collapse – “Collapse all headings”.
Now you can focus your attention better by only expanding a single paragraph. To go back to the original layout right-click and select Expand/Collapse – “Expand all headings” and the full document will show.
