Not sure whether this is a "bug" or just a "problem".

I would like to bind the keys on the SUN 3 I am using to useful EMACS
functions.  The keyboard has keys L1--L10 on the left and R1-R15 on the
right.  

Doing "C-q" followed by one of these keys gives as follows:
L1:   
L2:   
etc. except for R8, R12, R14 and R10 which give "C-p", "C-f" etc.
to make them standard "arrow" keys.

If I try to bind, say, L1 to forward search using :

(define-key global-map "^[[192z" 'isearch-forward)

I get an error-message about the key having an illegal prefix.
Some experimentation shows that this message is produced with
any key sequence that has "[" following the ESC character.

I have also noticed that *sometimes*, L1 produces "^[[23~" rather than
"", but can't identify under what circumstances.

Any experience on these problems?

Thanks.
