Throughout my project, I was trying to replace occurances of
            .append("\n")
with
            .append('\n')
I tried using Edit->Replace in Project(s) and gave the following find/replace params (I don't have regex checked):
     Find:         .append("\\n")
     Replace with: .append('\n')
But I end up with a file that has a physical line break after the first single quote :-(  If I try to escape the
backslash - e.g. .append('\\n')  - then the file ends up with two backslashes - which is also not what I want :-( 
Escaping backslashes further just compounds the number of backslashes and/or physical line breaks that appear in the file.

What makes the whole matter even more confusing is that the Edit->Replace in Project(s) doesn't work the same way as the
replace within a java file (ctrl-h).  There, I don't have to escape the backslash character in the Find and the
replacement string works as expected also:
     Find:         .append("\n")
     Replace with: .append('\n')

Why the difference?  And why doesn't Replace in Project(s) work with newlines as expected?
