Refresh files in NERDTree?

Question

How do I refresh file tree in NERDTree ?

If I use:

:!touch SomeNewFile

It is not rendered in the tree.

Answer 1

The NERD tree quick help is accessible from the NERD tree window by typing ? There I read:

" Filesystem mappings~
...
" r: refresh cursor dir
" R: refresh current root

These should do what you ask.

Answer 2

I use a custom map to refresh NERDTree:

nmap <Leader>r :NERDTreeFocus<cr> \| R \| <c-w><c-p>

Once set, Leader + r will do this for you:

• Switch to NERDTree
• Refresh the Root Node
• Switch back to the previous window

^{Note: My key map has a last step where it refreshes CtrlP after refreshing NERDTree}
