>I have a fairly large document (about 40 pages) that I have written when I knew nothing about styles. (Actually I still know very little about styles :)). But now I want to re-style this document. Mainly I want to have 4-step headings: Heading 1, Heading 2, Heading 3, and Heading 4. Therefore, everything will look consistent and when I click on Document Map button the document would look nice and structured. My question is, do you recommend that I create the new styles and add them to the existing list of styles of these document and then go through and changing headings from whatever non-styles they are to my new styles? Or is it better to delete all styles from the existing document (and there are tons of them for some reason) and start from scratch?

I think it's the same - you can always show only styles in use, so you get a filtered view on the styles. Just untag every paragraph - or whichever tool you have that will remove all formatting - and then just go about it. BTW, if you use outline view in Word (don't know what you're using, and doesn't really matter), you can just assign levels by tabbing and shift-tabbing header paragraphs and they automagically get assigned Heading 1, 2, etc. Or assign hotkeys for the same thing - ctrl+1 or alt+1 for heading 1 etc. That would speed up the process - just hunting for the combo, dropping it, scrolling, clicking... is too much work if you have to do it dozens of times (as I'd assume you'd have on 40 pages).
