While I was filling out a bug report to Apple, I realised I had sent
the wrong test code to this list.  My apologies.  Here is something
that will illustrate it without requiring non-standard libraries!

#!/usr/bin/python
import curses
import curses.ascii

def mainloop(scr):
    while 1:
        scr.keypad(1)
        curses.halfdelay(100)
        ch = scr.getch()
        if ch == "-1": scr.addstr(2, 0, '-1')
        try:
            scr.erase()
            scr.addstr(0,0, "%s, %s,  %s" %
            (curses.keyname(ch), curses.ascii.unctrl(ch), ch))
            scr.addstr(1,0, str(ch))
        except:
            pass
        scr.refresh()

if __name__ == "__main__":
#   locale.setlocale(locale.LC_ALL, '')
    print curses.wrapper(mainloop)
