Strategies for editing large documents

["Jeff Rafter" <jeffrafter@defined.net>]

I was wondering if anyone had any articles on how to edit (or develop an
editor) for large documents. I am looking for something that checks content
as you type and am struggling trying to figure out how to re-check only
changed sections.

Thanks,
