Discussion
The delegate can use this message as its cue to perform an action or select the attachment cell’s character. aTextView is the first text view in a series shared by a layout manager, not necessarily the one that draws cell.
The delegate may subsequently receive a textView(_:doubleClickedOn:in:at:) message if the user continues to perform a double click.
