crmode is an alias of cbreak.

The curses extension of ruby-1.7 provides those functions
such as Window#attron, Curses.color_pair and Curses::KEY_LEFT.
Here is an example code which shows how to deal with colors:

  win = Window.new(....)
  win.attron(color_pair(COLOR_RED)){
    win.box(...)
  }

and each colors must be initialized before like this:

  start_color
  init_pair(COLOR_BLUE, COLOR_BLUE, COLOR_BLUE)
  init_pair(COLOR_RED, COLOR_RED, COLOR_RED)
