Commands from richtextbox also in htmltextbox?

It would be wonderful if some commands what can be found in the richtextbox are also in the htmltextbox so you can search for example for a word and then color it like this as in a richtextbox.:
 Dim startindex As Integer
        For Each line As String In Me.RichTextBox1.Lines
            If line.StartsWith("Now") Then
                Me.RichTextBox1.Select(startindex, line.Length)
                Me.RichTextBox1.SelectionBackColor = Color.Yellow
            End If
            startindex += line.Length + 1
        Next
        Me.RichTextBox1.SelectionStart = 0
