global-set-key function needed

< pjb> quazimodo: for use-input-char, you could evolve it using a hash table to map the keys to functions, so that you can later easily (dynamically) add bindings, and turn it 
             into a full emacs! ;-)

 < pjb> Write a global-set-key function: 

``` lisp
(global-set-key  #\Vt (lambda (query-object) (kill-query-string-from (cur-y) query-object)))
```

or make it _query-object_.
