When opening ``helm-find-files`` via ``C-x C-f``, I can type to narrow the list of files to the desired one.

When I want to create a new file, and that file name matches an existing one, I am stuck::

  Find Files (C-l: Go up one level)                                                                       
  pageBanners.gql                                                                                         
                                                                                                        
  New file or directory                                                                                   
  [+] banners.gql


   *helm find files* L1    [1 File(s)]   C-h m:Help TAB:Act RET/f1..f12:NthAct C-!:Tog.suspend C-h c:Conf 
  Find files or url: /home/cweiske/tmp/banners.gql

Solution: Press ``C-v`` to go down to the "New file or directory" part of the window. ``M-v`` to go back.
