how to skip a boolean checkbox

i have this workbook that cycle's through a sheet (actually two) and i want to mark a particular shortcut as read. this is working but when i press the next or previous button (to cycle), it stops and doesn't jump over a true checkbox. will upload the workbook for you to see.

here is what i think needs to be configured:

Private Sub CheckBox1_Click()

    indexVBA = ThisWorkbook.Sheets("Formulas").Range("IndexVBA")
    indexExcel = ThisWorkbook.Sheets("Formulas").Range("IndexExcel")
    'test for listbox being "VBA"
    If ListBox1.Value = "VBA" Then
        'test for checkbox being "True"
        If CheckBox1.Value = True Then
            chkbxV(indexVBA) = True
            If indexVBA < 99 Then
                indexVBA = indexVBA + 1
                If chkbxV(indexVBA) = True Then
                    indexVBA = indexVBA + 1
                End If
            Else
                indexVBA = indexVBA - 1
            End If
            Sheets("Formulas").Range("A2") = indexVBA
            ListBox1_Click
            CheckBox1.Value = False
        Else
            chkbxV(itemVBA) = False
        End If
        Debug.Print "chkbxV(" & itemVBA & ") is " & chkbxV(itemVBA)
        
    Else
        
        If ListBox1.Value = "Excel" Then
        'do excel here
        End If
End Sub

i think that this is just a mess and will probably have to be completely rewritten.

also my next and previous seems to be working ok, but not sure if there needs to be coded added to it.
