It shows <kp-5>

Sorry, I was a bit in a hurry and forgot to include the backtrace.

I'll try to explain how I understand the problem :

It happens in widget-choose, where that function does :
 (define-key map (vector next-digit) function)
Here, next-digit is the integer ?5. Moreover there's a
default binding
 (define-key map [t] 'keyboard-quit)
which is what is triggered when I hit <kp-5>

Simply trying to bind [kp-5] to function there won't work either,
because further in the code, there is this test:
 (while (not (or (and (integerp char)
                      (>= char ?0) (< char next-digit))
                 (eq value 'keyboard-quit)))
where "char" is the symbol kp-5 (it is the integer ?5 in the
working case)

Does that make any sense ?
