This question comes from here: https://github.com/tpope/vim-fugitive/issues/1586

In a word, I'm using the two plugins: Nerdtree and vim-fugitive. What I need is when I execute :Git checkout mybr, I want to make Nerdtree be refreshed automatically.

So tpope told me that I could use autocmd User FugitiveChanged.

This is the first time that I see autocmd User. It seems that User means "never execute automatically". So I've tried to manually execute this in my vim: :doautocmd User FugitiveChanged.

However, nothing happend: no error but Nerdtree hasn't be refreshed either.

Did I do something wrong?

User means it is never executed by core Vim. Basically, it's a plugin who does doautocmd User X. Your business is to catch it with :augroup / :autocmd. So, yes, you did it wrong.
