If you want to remove line breaks, and put all text into a single paragraph, you can use the search string
\r\n
Notice that the R and N have switched places.
The only caveat here, however, is that spaces may not be added between merged sentences. This is easy enough to fix with two more quick search/replace queries.
1. Find all periods, and replace with period + space --- "." is replaced with ". "
2. For all sentences that previous had a proper space, an extra space has been added. To correct this, simply search/replace two spaces
-- a single space "_" is replaced with two spaces "__"
Easy enough.
