Select Multiple entry and remove in dropodown in excel vba

Hi,

I have got the following code from other website, But in case I click on something accidently and need to remove it without (hopefully) clearing the whole cell and starting over?

Private Sub Worksheet_Change(ByVal Target As Range)
'Updated: 2016/4/12
Dim xRng As Range
Dim xValue1 As String
Dim xValue2 As String
If Target.Count > 1 Then Exit Sub
On Error Resume Next
Set xRng = Cells.SpecialCells(xlCellTypeAllValidation)
If xRng Is Nothing Then Exit Sub
Application.EnableEvents = False
If Not Application.Intersect(Target, xRng) Is Nothing Then
xValue2 = Target.Value
Application.Undo
xValue1 = Target.Value
Target.Value = xValue2
If xValue1 <> "" Then
If xValue2 <> "" Then
If xValue1 = xValue2 Or _
InStr(1, xValue1, ", " & xValue2) Or _
InStr(1, xValue1, xValue2 & ",") Then
Target.Value = xValue1
Else
Target.Value = xValue1 & ", " & xValue2
End If
End If
End If
End If
Application.EnableEvents = True
End Sub
