The keypad and cursor keys have two modes - 'normal' and 'application'.  If
you hold down <control> and press the middle mouse button when in your xterm
window, you can see that application mode is normally off.  To enable it,
programs can use the keypad() curses function.  This uses the termcap entries
'ks' and 'ke' to turn application mode on and off, respectively.  Look what
the keypad and cursor keys generate after :

	printf "\e[?1h"
	printf "\e="
