In my answer to this question I wanted to break the lines to improve readability and indent some of the lines. The only way I could find to indent the lines was to use \quad Hitting one return doesn't cause a line break in the displayed text, just in the edit window. When I hit two returns, I get a double space. I also tried putting \ in my $\LaTeX$ but as I wasn't in display mode it didn't work. How do I get single returns and indents?
The best thing I can think of
is to end the preceding line with two whitespaces
(which creates a single line break)
and copy-paste several
at the beginning of next line.
(Turns out this is same method as in the link Martin posted.)
