Word SelectionChange 事件

问：

我在 MS Word 中使用 VBA（使用 Developer => Visual Basic 选项）

我尝试捕获当我滚动到文档中的不同页面（无论是通过鼠标还是键盘）时触发的事件 我尝试使用不同的事件名称（根据我在互联网上找到的内容），但没有任何发现

Private Sub ThisDocument_SelectionChange(ByVal Sel As Selection)
    ' Check if the user is scrolling (i.e., changing the selection)
    ' and display a message box.
    
    MsgBox "You are scrolling the document."
    
End Sub
Private Sub ThisDocument_WindowSelectionChange(ByVal Sel As Selection)
    ' Check if the user is scrolling (i.e., changing the selection)
    ' and display a message box.
    
    MsgBox "You are scrolling the document."
    
End Sub
Private Sub Document_SelectionChange(ByVal Sel As Selection)
    ' Check if the user is scrolling (i.e., changing the selection)
    ' and display a message box.
    
    MsgBox "You are scrolling the document."
    
End Sub

Private Sub Document_WindowSelectionChange(ByVal Sel As Selection)
    ' Check if the user is scrolling (i.e., changing the selection)
    ' and display a message box.
    MsgBox "You are scrolling the document."
    
End Sub

我在这里错过了什么？

谢谢
