<para>
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>
<para>
"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.
</para>
</footnote>
</para>

<para>
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.
</para>

<para>
Marks optionally have names; these can be convenient to avoid passing the 
#GtkTextMark object around.
</para>

<para>
Marks are typically created using the gtk_text_buffer_create_mark() function.
