Within both ‘Paragraphs’ pages, there is a search option located above the right hand side of the screen, just below the 'New Paragraph' button. This is outlined in red below.
A paragraph can be located by typing the name of the paragraph into the search box. Matching paragraphs will appear in the paragraphs shown on the right hand side of the tree structure.
This is a useful feature if you want a quick way of locating a paragraph when there are a large number shown on the screen.
