Sorry for the oddly-worded question - it's much more specific than it sounds. Namely, when you've prepared your design documents, outlined every scene, described every character, etc., how do you actually choose to write? For example: What program do you use to write, and why? How do you format your text? Size, font, spacing, etc. Do you write your entire work in a single document, or do you divide it into chapters, etc.?
