word VBA samples wanted

Hi,
I would appreciate some sample word/vba documents which show:
1. navigating around a word document using: range, paragraph, etc
2. using word as a standard document with input boxes (to key into)
3. using a standard document and populating "fields" with data from a database or input form. My issue is not getting the data but how to set up and maage the fields (words or paragraphs)

Simpler examples preferred
Your help is much appreciated

JeanRage thanks for the information I was having same problem but now I have the source of solution to ponder over
