SYNTAX            : LEFT

FUNCTION          : Moves cursor left within one row.

                    At the beginning of a line, the cursor is moved to
                    the end of the previous line.

                    If the horizontal scrolling region is entered, the
                    cursor no longer moves left. Instead, the text area
                    moves to the right. This only happens for as long as
                    there still is invisible text beyond the window
                    border.
