c++ - How to "text scroll" on a Text-Based Adventure Game setting?

Question

I am making a text-based PokeMon adventure game and I was wondering how to "text scroll" in the menu instead of making a:

cout << "MENU" << endl;
cout << "[N] New Game" << endl;
cout << "Mode: ";
cin >> option;

If you don't know what I mean by "text scrolling" then here is what I want:

#####MENU################################# Now when I press "s" or "down" that
>[N] New Game                            # ">" thing will go down to where the
+[L] Load Game                           # "+" symbol is. And when they press
#[O] Options                             # "enter" they are taken to the loading
#0.0.1a                                  # screen. This also works by pressing
########################################## the "w" or "up" keys.

Is there a way to do it or do I need an external library?
