in the process of revising my current novel, I'm typing in every word again, well of course the parts that are changed, but even the parts that could be cut'n'pasted verbatim

I think that's a really good way of doing it; it stops you being lazy about revisions (because, basically, it's no more work to type up a slightly tweaked version than it is to blankly repeat whatever you originally wrote) and forces you to think about what you've written as a whole while you're going along, rather than focusing in on perceived problem spots.
