I am interested in doing key mappings like Vi and emacs. Did look 
through the code a bit
.
Could you tell me in brief how you map something like C-x C-c.

1. Do you use some ncurses feature like waiting / delay for another key.

2. Or when C-x is pressed, you check your structure to see if its 
mapped, and if there's something more like a C-c, then you wait more.

3. something else. Like after the C-x you do another getch() for the 
next character.

Have you faced problems handling Alt-keys ? Do you find that 2 key codes 
are generated (I am on a mac, btw.). I am fine with F1 etc using 
TERM=screen.
