Why not just use the mouse wheel in combination with some keyboard shortcuts...
Mouse wheel to scroll fast or slow.
Ctrl+Up and Ctrl+Down to quickly go to the top or bottom of the list.
Page Down and Page Up to quickly navigate through the list.
Update
You can use this macro to automatically scroll:
Public interval As Date
Sub scroll_down()
interval = Now + TimeValue("00:00:01")
limit = Range("A" & Rows.Count).End(xlUp).Row
Selection.Offset(1, 0).Select
If Selection.Row >= limit Then Range("A1").Select
Application.OnTime interval, "scroll_down"
End Sub
Sub stop_scroll()
Application.OnTime EarliestTime:=interval, Procedure:="scroll_down", Schedule:=False
End Sub
