In 2004 for the Mac, you do not want to cut and paste from a lot of different documents.
I reset the "normal" template default but it doesn't matter. If you bump things up, suddenly a paragraph will revert to a different font and size, and sometimes margin.
Worse, that damn little thing that sometimes appears at the end of sentences with options for changing formats -- I was tired of it always appearing where I was trying to create a bulleted list, but there was no option to move it out of the way.
So I optioned clicked to reset some settings.
After that, if I added a character or words to a paragraph, everything would suddenly shift on a line-by-line basis, creating huge gaps that had to to be manually corrected (no, not justified text). If you then decided to tweak the line again, the same thing happened.
I looked and played with different settings but could never correct the behavior.
This is not an experience you want when creating a long document with a short deadline.
