Here is what i have for so far
It copies only one selected text.
But i want to copy to clipboard only highlighted like in the picture shown

Code:

---

If RichTextBox1.SelectedText <> "" Then
            'Copy the information to the clipboard
            Clipboard.SetText(RichTextBox1.SelectedText)
        Else
            'If no text was selected, print out an error message box
            MsgBox("No text is selected to copy")
        End If

---

and this copy all but not in new line

Code:

---

If True Then
            ' Check if selection exists and that it's not null
            If RichTextBox1.SelectionLength > 0 Then
                ' Copy the selected text to the Clipboard
                Clipboard.SetText(RichTextBox1.Text, TextDataFormat.Text)
            End If
        End If

---

Multiple selection is not possible in a RichTextBox so you've lost me!

Ok if it is inpossible as you say so maybe you will know how to add highlighted from richtextbox to textbox or listbox from listbox to textbox all selected
I just wanna add only matches not all
