Look up key binding for command

[Michael Ludwig-3]

Let's say I'm exploring some feature, like ":help quickfix".
I then see :cnext (also :cn) in the documentation, and I'm
wondering whether it's bound to some key mapping. What's the
best way to find out? I did the following, but there might
be a better way:

  :redir hhh.txt
  :map
  :redir end
  :e hhh.txt
  /cnext

(By the way, :cnext isn't bound to any command in my setup.)

Note vim normal commands are done internally by vim and not by a :map command.
So for example you will not find CTRL-W_CTRL-N (:help CTRL-W_CTRL-N) in any
map though it behaves like :new command. Usually, the help file is written in
such a way that ex-command is written together with the corresponding normal
command, like in: ":help :new" and ":help CTRL-W_CTRL-N".

However, there are many maps defined by plugins and that's why all the :map commands
are useful (knowing the key, e.g. :map <F10>). I wrote a plugin to search in
right or left side of a map:
    http://www.vim.org/scripts/script.php?script_id=3767

You can also use :helpgrep command to grep in the docs (consult ":help :helpgrep")

I see.

Works fine. I can see that you're also using :redir and :map and
its brethren to get the mapping. As far as I can see, the current
release only searches the right-hand side of the mapping, though.

One observation:

    if len(found_maps) > 0
        echo join(found_maps, "\n")
    else
        echohl WarningMsg
        echo "No such map"
        echohl Normal
    endif

Maybe "No matches found" would be a more suitable message here.

Thanks. All very helpful.

with :Map! you the pattern matches against the whole output of :map command
(except the mode in the first column).

Indeed - works fine. Thanks.
