在：h NERDTree：
:NERDTreeFind :NERDTreeFind
Find the current file in the tree. If no tree exists for the current tab,or the file is not under the current root,then initialize a new tree where
the root is the directory of the current file.
我不认为它默认绑定到任何东西，所以你必须自己做一个键绑定。
nmap,n :NERDTreeFind<CR>
是什么出现在我的.vimrc，一起
nmap,m :NERDTreeToggle<CR>
