And to see the function itself you can do

M-x find-function-on-key RET your_key RET

,----[ C-h f find-function-on-key RET ]
| find-function-on-key is an interactive compiled Lisp function in
| `find-func.el'.
| 
| It is bound to C-h K, <f1> K, <help> K.
| 
| (find-function-on-key key)
| 
| Find the function that key invokes.  key is a string.
| Set mark before moving, if the buffer already existed.
| 
| [back]
`----

And bind it to for exemple:

,----
| (global-set-key (kbd "\C-hK") 'find-function-on-key)
`----
