You could use a pair of macros to achieve the functionality required, with buttons on the QAT (Quick Access Toolbar) or Ribbon to call then e.g.
Code:
Sub GoToNextPage()
Selection.GoTo What:=wdGoToPage, which:=wdGoToNext, Count:=1
End Sub
Sub GoToPreviousPage()
Selection.GoTo What:=wdGoToPage, which:=wdGoToPrevious, Count:=1
End Sub
