<p>When I want to find the command bound to C-u M-. using C-h k, it turns out that emacs gives me the command bound with C-u. What should I do ?</p>

<p><code>C-u</code> is provides a prefix argument to the function called after it (as you can see from its docs). Access the documentation for <code>M-.</code> and then look there for what happens when the function receives a prefix argument. There's no separate documentation for <code>C-u M-.</code> since it is not separate function.</p>

Emacs, describe-key Command, C-h k
