// It turns out people don't really know how to handle Alt+ch, or F[1, 12] keys
// etc. in ncurses apps. Even StackOverflow is full of wrong answers and ideas.
// The key idea is to skip ncurses' key handling and read stuff from the stdin
// buffer manually. Here's a demo. Run this and start typing. ESC to exit.
//
// To compile:
//
// $ gcc demo.c -o demo -lncurses -std=gnu11

#include <ncurses.h>
