+ * SECTION:gtktextmark
+ * @Short_description: A position in the buffer preserved across buffer modifications
+ * @Title: GtkTextMark
+ *
+ * You may wish to begin by reading the <link linkend="TextWidget">text widget
+ * conceptual overview</link> which gives an overview of all the objects and data
+ * types related to the text widget and how they work together.
+ *
+ * A #GtkTextMark is like a bookmark in a text buffer; it preserves a position in
+ * the text. You can convert the mark to an iterator using
+ * gtk_text_buffer_get_iter_at_mark(). Unlike iterators, marks remain valid across
+ * buffer mutations, because their behavior is defined when text is inserted or
+ * deleted. When text containing a mark is deleted, the mark remains in the
+ * position originally occupied by the deleted text. When text is inserted at a
+ * mark, a mark with <firstterm>left gravity</firstterm> will be moved to the
+ * beginning of the newly-inserted text, and a mark with <firstterm>right
+ * gravity</firstterm> will be moved to the end.
+ *
+ * <footnote>
+ * "left" and "right" here refer to logical direction (left is the toward the start
+ * of the buffer); in some languages such as Hebrew the logically-leftmost text is
+ * not actually on the left when displayed.
+ * </footnote>
+ *
+ * Marks are reference counted, but the reference count only controls the validity
+ * of the memory; marks can be deleted from the buffer at any time with
+ * gtk_text_buffer_delete_mark(). Once deleted from the buffer, a mark is
+ * essentially useless.
+ *
+ * Marks optionally have names; these can be convenient to avoid passing the
+ * #GtkTextMark object around.
+ *
+ * Marks are typically created using the gtk_text_buffer_create_mark() function.
