My macro for copy/paste was broken because the MoveMode value to InsertContents in overwrite mode changed from 4 to 6.
Before the update to LO 5, my using MoveMode value = 4 inserted contents in overwrite mode.  After the update to LO 5, MoveMode value = 4 inserts contents in insert mode!

Macro snippet:

dim argsPasteT(5) as new com.sun.star.beans.PropertyValue
	argsPasteT(0).Name = "Flags"
	argsPasteT(0).Value = "SVD"
	argsPasteT(1).Name = "FormulaCommand"
	argsPasteT(1).Value = 0
	argsPasteT(2).Name = "SkipEmptyCells"
	argsPasteT(2).Value = false
	argsPasteT(3).Name = "Transpose"
	argsPasteT(3).Value = true
	argsPasteT(4).Name = "AsLink"
	argsPasteT(4).Value = false
	argsPasteT(5).Name = "MoveMode"
	argsPasteT(5).Value = 6
	dispatcher.executeDispatch(document, ".uno:InsertContents", "", 0, argsPasteT())
rem---update to Libre Office v5.1 changed MoveMode value for overwrite from 4 to 6  ---no notification of this change!
