You cannot map to modifier keys (like Ctrl, Shift, Alt) alone; they can only be used in combination with other keys that represent printable characters (like <C-a> = Ctrl + A). That's mostly due to the fact that terminals do not send keypress events for modifier keys alone. There are unfortunately even limitations in those combinations (also in GVIM). Some key combinations, like Ctrl + non-alphabetic cannot be mapped, and Ctrl + letter vs. Ctrl + Shift + letter cannot be distinguished.
