Sometimes we want to take one long chapter and split it in two. It might be because we’ve headed off in a different direction, or because it was just getting unwieldy. Or it might be because you’ve imported a Word document with a whole novel in it and need to split out each of the chapters.
It doesn’t matter why, this is how it works:
In the chapter sidebar there is a link to Split. If you hit this your sidebar closes and you can drag your mouse to the point where you need to split the chapter. If you then split it, it prompts you to choose a title for your new chapter, then creates that chapter with the content below. It’s as simple as that.
