+#### Override filetree key bindings
+
+If you want to override the default key bindings in filetree windows. You can use User autocmd in bootstrap function. for examples:
+
+```vim
+function! myspacevim#before() abort
+    autocmd User NerdTreeInit
+        \ nnoremap <silent><buffer> <CR> :<C-u>call
+        \ g:NERDTreeKeyMap.Invoke('o')<CR>
+endfunction
+```
+
+Here is all the autocmd for filetree:
+
+- nerdtree: `User NerdTreeInit`
+- defx: `User DefxInit`
+- vimfiler: `User VimfilerInit`
+
 ## General usage
 
 The following key bindings are the general key bindings for moving the cursor.
