| You can explore which keys do what for any given buffer by typing | C-h b | and searching for likely-looking function names. You can retrieve | the documentation for a function by hitting C-h f.
Or, now that help output is nicely hyperlinked, just click on the function name next to the key sequence in the help buffer. There is even a [back] button in the resulting help buffer to get you back to the list, in case the function turned out to be irrelevant.
