Discussion
This method is invoked after the user clicks cell at the specified charIndex location in aTextView. If the textView(_:draggedCell:in:event:at:) is not used, this method and textView(_:write:at:to:type:) allow aTextView to take care of attachment dragging and pasting, with the delegate responsible only for writing the attachment to the pasteboard.
