how to move current word caret position into previous word in richtextbox wpf?

I am writing a application using WPF C# Windows application.i want to navigate word by word in that richtextbox content.how to i done it. i already tried to move current word to next word navigation.its work. i am using the below code.

TextPointer starting = txtAppendValue.Document.ContentStart;
            startval = txtAppendValue.CaretPosition;
            text = startval.GetTextInRun(LogicalDirection.Backward);
            newWord = txtAppendValue.CaretPosition.GetNextInsertionPosition(LogicalDirection.Forward);
            if (newWord != null)
            {

                txtAppendValue.CaretPosition = newWord;
                txtptrCaret = txtAppendValue.CaretPosition;
                NextStringvalue = txtptrCaret.GetTextInRun(LogicalDirection.Forward);
                {
                    txtptrCaret = txtAppendValue.CaretPosition;
                    range1 = new TextRange(starting, txtptrCaret);
                    indexInText = range1.Text.Length;
                }}

this below line newword text pointer to give a next word to end of the content.

newWord = txtAppendValue.CaretPosition.GetNextInsertionPosition(LogicalDirection.Forward);

So now how to i get an previous word and all other words text pointer?

Note: i already get the previous words using content start and caretposition.but it gives like strings. i want textpointer value to move each previous word.

You could use the MoveRightByWord and MoveLeftByWord commands for this:

EditingCommands.MoveLeftByWord.Execute(null, richTextBox);

According to the documentation, both commands are supported by RichTextBox.

Note, though, that when the input caret is within a word, this command moves it to the start of that word, not to the start of the previous word.
