Carriage return in Field Title

Is it possible to insert a line break in the field: Title ?

I do not think it is possible to enter an actual line break in the field Title.
The main reason is that JabRef files are, by default, designed to be used by bib(la)tex, and it is bib(la)tex’s job to break the lines.
Maybe inserting a command `\newline` (or `\protect\newline`) in the title field may affect bib(la)tex behavior (I have not tested).

Where does your need to insert a line break in the title come from?

Thank you for the reply. LaTeX commands `\newline` or `\protect\newline` does not work.
