 				Returns the [PopupMenu] of this [TextEdit]. By default, this menu is displayed when right-clicking on the [TextEdit].
+				You can add custom menu items or remove standard ones. Make sure your IDs don't conflict with the standard ones (see [enum MenuItems]). For example:
+				[codeblocks]
+				[gdscript]
+				func _ready():
+				    var menu = get_menu()
+				    # Remove all items after "Redo".
+				    menu.item_count = menu.get_item_index(MENU_REDO) + 1
+				    # Add custom items.
+				    menu.add_separator()
+				    menu.add_item("Insert Date", MENU_MAX + 1)
+				    # Connect callback.
+				    menu.id_pressed.connect(_on_item_pressed)
+
+				func _on_item_pressed(id):
+				    if id == MENU_MAX + 1:
+				        insert_text_at_caret(Time.get_date_string_from_system())
+				[/gdscript]
+				[csharp]
+				public override void _Ready()
+				{
+				    var menu = GetMenu();
+				    // Remove all items after "Redo".
+				    menu.ItemCount = menu.GetItemIndex(TextEdit.MenuItems.Redo) + 1;
+				    // Add custom items.
+				    menu.AddSeparator();
+				    menu.AddItem("Insert Date", TextEdit.MenuItems.Max + 1);
+				    // Add event handler.
+				    menu.IdPressed += OnItemPressed;
+				}
+
+				public void OnItemPressed(int id)
+				{
+				    if (id == TextEdit.MenuItems.Max + 1)
+				    {
+				        InsertTextAtCaret(Time.GetDateStringFromSystem());
