title: Ctrl+S (horizontal split) not working with Command-T in vim
body: <p>I can't get the horizontal split to work. Ctrl+enter does nothing, Ctrl+S does nothing.</p>
  
  <p>I've been googeling this for a bit and the only solutions I've found so far are related to OSX.</p>
  
  <p>On both Arch Linux and Ubuntu, having same problem (but also the same config).</p>
  
  <p>I'm not using Janus or anything like it, just a very basic config</p>
  
  <pre><code>set t_Co=256
  set tabstop=2
  set expandtab
  set shiftwidth=2
  set fileencoding=utf-8
  set encoding=utf-8
  set termencoding=utf-8
  set showcmd
  filetype plugin indent on
  "color molokai
  syntax enable
  autocmd! BufNewFile * silent! 0r ~/.vim/skel/tmpl.%:e
  set laststatus=2 " Always show the statusline
  
  set backspace=indent,eol,start  " backspace through everything in insert mode
  
  "" Searching
  set hlsearch                    " highlight matches
  set incsearch                   " incremental searching
  set ignorecase                  " searches are case insensitive...
  set smartcase                   " ... unless they contain at least one capital letter
  
  call pathogen#infect()
  colorscheme jellybeans
  " use comma as &lt;Leader&gt; key instead of backslash
  let mapleader=","
  
  " Double &lt;Leader&gt; to switch between buffers
  nnoremap &lt;leader&gt;&lt;leader&gt; &lt;c-^&gt;
  " double percentage sign in command mode is expanded
  " to directory of current file - http://vimcasts.org/e/14
  cnoremap %% &lt;C-R&gt;=expand('%:h').'/'&lt;cr&gt;
  
  map &lt;leader&gt;f :CommandTFlush&lt;cr&gt;\|:CommandT&lt;cr&gt;
  map &lt;leader&gt;F :CommandTFlush&lt;cr&gt;\|:CommandT %%&lt;cr&gt;
  </code></pre>
  
  <p><code>
  [~]$ ls .vim/bundle<br>
  rbenv:system 
  command-t  jellybeans.vim  snipmate-snippets  tlib_vim  vim-addon-mw-utils  vim-powerline  vim-snipmate
  </code></p>
  
  <p>I was hoping someone would be able to shed some light on this, it's getting really frustrating.</p>
  
  <p>Not entirely sure whats wrong but it have work occasionally, but not at all right now.</p>
  
  <p>Pressing CTRL+S does nothing, shift+enter just opens it normally in the current buffer and ctrl+enter just hops down the search results list in Command-T.</p>
