Getting _help_ on last response from C-h c

[Tim Johnson]

On GNU Emacs 24.3.1 :
Let's say I type C-h c C-M-a

Help returns 
C-M-a runs the command beginning-of-defun

As I understand it, to get _help_ on beginning-of-defun, I have to
then type 
C-h f beginning-of-defun

Is there a way that would return both the binding and help on the
bound function?

Example:

C-h x (currently undefined) C-M-a
would return
C-M-a runs the command beginning-of-defun
*and*
beginning-of-defun is an interactive compiled Lisp function ...

Thanks
