如何进行编码 ENTER 键，以在 Word 中受保护的表单中的窗体字段之间移动

Sub EnterKeyMacro()
' Check whether the document is protected for forms
' and whether the protection is active.
   If ActiveDocument.ProtectionType = wdAllowOnlyFormFields And _
   Selection.Sections(1).ProtectedForForms = True Then
      ' Retrieve the bookmark of the current selection.
      ' This is equivalent to the name of the form field.
      myformfield = Selection.Bookmarks(1).Name
      ' Go to the next form field if the current form field
      ' is not the last one in the document.
      If ActiveDocument.FormFields(myformfield).Name <> _
      ActiveDocument.FormFields(ActiveDocument.FormFields.Count) _
      .Name Then
         ActiveDocument.FormFields(myformfield).Next.Select
      Else
         ' If the current form field is the last one,
         ' go to the first form field in the document.
         ActiveDocument.FormFields(1).Select
      End If
   Else
   ' If the document is not protected for forms,
   ' insert a tab stop character.
      Selection.TypeText Chr(13)
   End If
End Sub

Sub AutoNew()
 ' Do Not protect the template containing these macros.
   CustomizationContext = ActiveDocument.AttachedTemplate
   ' Bind the ENTER key to the EnterKeyMacro.
   KeyBindings.Add KeyCode:=BuildKeyCode(wdKeyReturn), _
   KeyCategory:=wdKeyCategoryMacro, Command:="EnterKeyMacro"
   ' Reprotect the document with Forms protection.
   ActiveDocument.Protect Type:=wdAllowOnlyFormFields, NoReset:=True
End Sub

' This macro will reassign the ENTER key when you open an existing
' Word form fields document.
