SYNTAX            : DOWN

FUNCTION          : Moves cursor down within one column.

                    If column movement ends at a line which is shorter
                    than the original column number, the cursor is moved
                    to the end of that line. The original offset is
                    remembered, so that further cursor movement (either
                    Cursor down or Cursor up) will revert to the original
                    column as soon as a line is reached which is long
                    enough.

                    If the vertical scrolling region is entered, the
                    cursor no longer moves down. Instead, the text area
                    moves up.
