Fn + [KEYS] question

[Xiangfu Liu <xiangfu.z@gmail.com>]

Hi

I know in the IBM laptop, you use Fn + F1 to do something.
I want [Fn + U = 7] in my device. 
when you press Fn + U in the terminal it will display '7'.


I look into the keyboard.c file.
but don't know which function is handle the Fn key?

there is [1] in the keyboard.h file. I don't know 
which Fn key belong. is it KT_SHIFT???

thanks for any advice. 


[1] -------------
#define KT_LATIN	0	/* we depend on this being zero */
#define KT_LETTER	11	/* symbol that can be acted upon by CapsLock */
#define KT_FN		1
#define KT_SPEC		2
#define KT_PAD		3
#define KT_DEAD		4
#define KT_CONS		5
#define KT_CUR		6
#define KT_SHIFT	7
#define KT_META		8
#define KT_ASCII	9
#define KT_LOCK		10
#define KT_SLOCK	12
#define KT_DEAD2	13
#define KT_BRL		14
