Text list - re-showing widget with PICKED at the top position

Hello REBOLers, A very undocumented feature, again ;-) : How can I arrange that after programatically selecting the PICKED element from the text list, the widget redraws itself with the PICKED element at the top of the list? More generally, how can I set the slider of a text-list in a way that after SHOW any given line of DATA will be positioned at any given part of the viewable area (top, middle etc.) of the text list? Thank you for the kind input! -- Best regards, Geza mailto:[geza67--freestart--hu]
