<div class="markdown level1 remarks"><p>
This method can be used to linearly traverse a <a class="xref" href="C1.WPF.RichTextBox.Documents.C1Document.html">C1Document</a> tree.
</p>
<p>
Start and end tags in each <a class="xref" href="C1.WPF.RichTextBox.Documents.C1TextElement.html">C1TextElement</a> count as items for the traverse, for instance
if the position is in an element with children, a position at offset 1 will be the <a class="xref" href="C1.WPF.RichTextBox.Documents.C1TextElement.ContentStart.html#C1_WPF_RichTextBox_Documents_C1TextElement_ContentStart">ContentStart</a>
of the <a class="xref" href="C1.WPF.RichTextBox.Documents.C1TextElement.html">C1TextElement</a> where this C1TextPointer is positioned.
</p>
<p>
If this C1TextPointer is positioned in a <a class="xref" href="C1.WPF.RichTextBox.Documents.C1Run.html">C1Run</a> then it traverses the text of the C1Run.
