cursor

   1. <hardware> A visually distinct mark on a display indicating
   where newly typed text will be inserted.  The cursor moves as
   text is typed and, in most modern editors, can be moved around
   within a document by the user to change the insertion point.

   {application program} to point to a row of data.  The position
   of the {row} is within a {table} or {view}, and the cursor is
   used interactively so select rows from columns.
