  Moves the cursor left one character at a time.

  Key:   EVE default             VT100 keypad

  Usage notes:

  o  If the cursor is free (default setting), you can move it anywhere in
     the buffer, whether text is there or not. For example, if the left
     margin is greater than 1, you can move left of the left margin, which
     is useful in creating tables and lists.

  o  If the cursor is bound, then from the start of a line, it moves to the
     end of the previous line (if any), as in EDT, WPS, and other editors.
