I read in another thread about line breaks when submitting sample chapters to an agent/publishers. From the posts, I read that when you have a line break in your work, you will use a # to indicate it. However, I just want to be clarified, what exactly are line breaks? Are they the three asterix/or spacing used to indicate the scene change or when a person reads a letter? If they are, would we insert two line breaks instead of one to indicate the scene change? Because right now, my manuscript is formatted as such that I use double breaks to indicate a scene change (instead of the three asterixs) and a single break when a person is reading a letter. Would I insert two # for the scene changes and a single # for the reading of the letters?
