   def moveLeft(self): 
      y, x, q, p = self.position()
      schar = self.editor.doc.getStartchar(q)
      if x: self.editor.moveCursor(y, x - 1)
      elif schar: 
         start = max(0, schar - self.editor.maxx - 5)
         self.editor.doc.setStartchar(q, start)
         self.drawline(y)
         self.editor.moveCursor(y, min(p - 1, self.editor.maxx))
      elif (y or self.editor.doc.startline): 
         self.moveUp()
         self.endOfLine()

Which became:

   def move_left(self): 
      screen, doc = self.context()

      if not screen.start_of_line(): 
         self.move_cursor_left()

      elif screen.start_of_line() and \
           not doc.first_line() and \
           not screen.hidden_left(): 
         self.move_up()
         self.end_of_line()

      elif screen.start_of_line() and \
           screen.hidden_left(): 
         self.show_left_section()
         self.end_of_screen_line()
