+# Read In The Contents Of A Rails File
+
+The [`rails.vim` plugin](https://github.com/tpope/vim-rails) allows you to
+quickly navigate to specific types of files with the `E` prefix. For
+instance, `:Emodel` will scope you to just the models directory.
+
+You can use this same approach with the `D` prefix. Instead of navigating to
+specified file though, this will read in the contents of that file into the
+current buffer.
+
+Do you need to copy and tweak the contents of a similar view? Open up your
+new view file (e.g. `:Eview posts/edit.html.erb`) and then enter `:Dview
+posts/new` to quickly copy in its contents.
