th the <B>element</B> command and
      feedback areas are painted using the <B>feedback</B> command. <P>

      The "<B>paint cursor</B>" option picks the layers underneath the
      position of the (X11) cursor and fills the cursor box with these
      types.  However, when no material (e.g., "space") is present under
      the cursor, then all material and labels are erased from the
      area of the cursor box. <P>

      The "<B>paint pick</B> <I>x y</I>" option works like "<B>paint
      cursor</B>",
