VBA Checkbox to Listbox (uncheck option to remove array) - vba

Question

I am struggling with a simple thing and cannot resolve it. I have a userform that user can populate from a textbox manually. I decided to add a checkbox as well to allow the user to populate the same listbox with a specific list of items. To do it,I made a simple checkbox with array. It works perfectly fine. But obviously keeps adding the items every time you check and uncheck it.
Private Sub Checkbox1_Click()
Dim mylist(7) As String
Dim i As Long
mylist(0) = "time"
mylist(1) = "hour"
mylist(2) = "how"
mylist(3) = "test"
mylist(4) = "number"
mylist(5) = "sent"
mylist(6) = "memo"
mylist(7) = "value"
For i = 0 To 7
If CheckBox1.Value = True Then
Finallist.AddItem mylist(i)
End If
Next i
End Sub
I can populate the list when the checkbox is checked with the code above, but struggling to remove the array items from the list when the user unchecks the listbox. I simply need to remove the same items from listbox when user unchecks the same checkbox.
I tried the following solution after the code, but seem to be making something very wrong with it, I understand. Just totally stuck....Could someone help me please?
If checkobx.value=false then
For i = 0 To 7
For j = 0 To FinalList.ListCount - 1
If InStr(Final.List(j), mylist(i)) > 0 Then
Finallist.RemoveItem mylist(i)
End If
Next j
Next i
end if

Try this (explanations in comments and untested):
If CheckBox1.Value Then ‘ if checkbox checked
For i = 0 To 7
NegKeyList.AddItem interrlist(i)
Next
Else ‘otherwise
Dim i As Long
For i = NegKeyList.ListCount - 1 To 0 Step -1 ‘ loop through listbox items from last one backwards
If Not IsError(Application.Match(NegKeyList.List(i), interrlist,0)) Then NegKeyList.RemoveItem i ‘ if current listbox item matches any interrlist array item then remove it from listbox
Next
End If
