vim-go: Anyone knows a good way to close both quickfix and location list with one shortcut?

Hey vim users. I am trying to find a good way to close both quickfix and location list with one shortcut.

I am currently using some parts of the vim-go author's .vimrc like this:

let mapleader = ","

" Some useful quickfix shortcuts for quickfix
map <C-n> :cn<CR>
map <C-m> :cp<CR>
nnoremap <leader>a :cclose<CR>

Which is great for quickly closing the quickfix window. But what about location list? Can both be closed with 1 shortcut?

If not, care to share your favorite 2 shortcuts for closing each one of them?

Why not just:

nnoremap <silent> <leader>a :cclose<CR>:lclose<CR>

Thanks! This seems to be working fine. Can you tell me the reason why you added <silent> in front?

Suppresses non-error messages and doesn't add them to the message history. See :help silent for more info.

I'm on mobile so I can't link to the documentation , but you can configure the vim-go plugin to open everything in a quickfix window.

Thanks for the reply. I'd rather not do that. I am pretty sure there is a very good reason some commands choose what they choose.
I am going with this command for now as it seems to be solving the problem:

nnoremap <silent> <leader>a :cclose<CR>:lclose<CR>

there are plugins for this. of course not related to vim-go. 
it is a vim issue to close less important or supporting type of buffers. 
my personal preference is https://github.com/szw/vim-smartclose

there are plugins for this.

I try to use as less plugins as possible but I would probably use something like that if this command didn't solve the problem:

nnoremap <silent> <leader>a :cclose<CR>:lclose<CR>

Thanks for the reply.
