    writefln("\nI'm going to ask you to press 10 keys (I promise it's painless).\n"
    "Certain keys don't count, but the whole alphabet is fair game.\n");

    for(int i = 0; i < 10; i++) {
        version(Windows) {
            writef("Press key: %d\t", i);
            k = getch();
        }
        version(linux) {
            writef("Press key (follow with return): %d\t", i);
            k = cast(char) getchar();
        }
        version(OSX) {
            // Unfortunately, merely using getchar() does not disable stdin and readline buffering.
            writef("Press key (follow with return): %d\t", i);
            k = cast(char) getchar();
        }
        writef("[%s]\t", k);    /* print the character pressed */

        writefln("[%d]\n", k);  /* print ASCII code for key */

        char enter = cast(char) getchar();

    }
    writefln("\nThe End.\n");
}
