 ## Messages
 
-### CellHighlighted
+### ::: textual.widgets.DataTable.CellHighlighted
 
-The `DataTable.CellHighlighted` message is emitted by the `DataTable` widget when the cursor moves
-to highlight a new cell. It's also emitted when the cell cursor is re-enabled (by setting `show_cursor=True`),
-and when the cursor type is changed to `"cell"`.
