Text marks (Gtk::TextMark) act as if they were invisible cursors within the text, changing position depending on how the text is edited. For instance, if the text is added before the mark, it (the mark) will move to the right so that it remains at the same textual position.
-By default, text marks have((*gravity*))set to the right, hence a text mark will move to the right as new text is added. If text is removed the mark will move between the two pieces of text on either side of the removed text. Then if the text is inserted at that position, because of its right gravity setting, the mark will remain on the right side of the inserted text. You can see that the text mark behaves just like a cursor in most text editors.

:Text Mark Visibility:
By default, text marks are invisible within the text, however, you can make them visible by setting Gtk::TextMark#visible=(boolean) to true.
