To shift text around as you would on a scrolling alphanumeric terminal screen.
key - The identifier returned by a previous Insert_Text() or Insert_Text_With_Encoding() . left_scroll - The amount the string or the block should be shifted to the left. Can also be negative, to give a right shift. up_scroll - For future compatibility, specify as zero.
Columns and rows are shifted the specified distance within the original text string. Characters that are shifted "off the edge" of the original are discarded—when (if) you scroll back again, you will need to manually reinsert them. Characters that are shifted "onto the edge" start out filled with blanks.
String Cursors, if any, scroll with their characters.
