Mr Bill,
This is a freebie, but this also isn't a code writing service and you should make some attempt before asking for the solution on a platter.
Code:
Sub ScratchMacro()
'A basic Word macro coded by Greg Maxey
Dim oRng As Range
Set oRng = ActiveDocument.Range
With oRng.Find
.Text = "Chapter [0-9]@"
.MatchWildcards = True
While .Execute
oRng.Move wdParagraph, 2
oRng.Paragraphs(1).Style = "Normal" 'You should create some named style for your first paragraphs and replace "Normal" with it.
oRng.Collapse wdCollapseEnd
Wend
End With
lbl_Exit:
Exit Sub
End Sub
