OOOOOPPPPPS!!!!!!
Joe, you are right. I went through the list in two sessions and inverted the selections in the second group and then used that as the incorrect key.
As a result my key is the wrong way as it relates to the second half of items. 'Y' should relate to deleting items not keeping them.
N=don't delete, keep it
Y=not needed so can disable or uninstall
?=it depends upon whether you want it, use it or identify precisely what it is
The corrected list is attached.
Very sorry
