This mail is not directly related to this subject.
But, I want to talk about the keyboard interface.

If "bits" are gaining some amount of currency as ad hoc standard,
"function-keys" are also gaining some amount of currency as ad hoc standard,
in japan. (I am not talking about the character issues here.
I am talking about the ad hoc standard for keyboard interfaces)

There are now MANY terminals/personal computers that have "function-keys"
in Japan.

Actually, there are discussions about the standard interface for  "function-keys" in CL in japan.
I was asked the possibility of the standard for it.
Lisp based interactive system faces the problem.
There arises a portability problem.
Furthremore many editor/word processing software in japan use  function keys.
The semantics for the function keys may vary. There may be 10 function keys physically,
and with shift-key they act as a command pannel for 20 functions.
The meaning of the each key is guided in CRT. 
Or a guide pad for each software is provided for user convinience.

I wonder this type of standardization for interface is japan domestic or no ?
