I’m going to have to try this Word function to keep track of  story developments.  I took a quick look at it (View –> Document map in Word 2003), and the display  reminds me of the bookmarks in a PDF file.  Because I find the the PDF bookmarks useful, I don’t see why this wouldn’t be, too.  I also like playing with functions like this.  I wouldn’t be surprised if, in a previous life, I was a typesetter — that’s when I wasn’t moonlighting as a tea-swilling cook.

My usual style is to work with separate Word.docs for individual chapters.  The thought of scrolling through enough pages to make a book made me cross-eyed, even without having tried an entire novel in one document.
