Add this to the plugin. It needs to be added to a file such as: ~/.vim/nerdtree_plugin/mymapping.vim. The exact location will depend on what plugin manager you use for vim. e.g. for Plugged it is ~/.vim/plugged/nerdtree/nerdtree_plugin/mymapping.vim

This code adds a mapping for the enter key to open files in a new tab while just expanding/collapsing directories. For the new tabs it also mirrors the NERDTree so it can be shared between tabs.

call NERDTreeAddKeyMap({
  \ 'key': '',
  \ 'scope': "Node",
  \ 'callback': 'OpenInNewTab',
  \ 'quickhelpText': 'open node' })


" FUNCTION: s:openInNewTab(target) {{{1
function! OpenInNewTab(node)
  if a:node.path.isDirectory
    call a:node.activate()
  else
    call a:node.activate({'where': 't'})
    call g:NERDTreeCreator.CreateMirror()
    wincmd l
  endif
endfunction
