title: opening emacs buffer in new horizontal or vertical split window using helm
body: <p>How would I bind a key to open up a buffer or file in helm in a new vertical or horizontal split? (BTW, I'm using spacemacs).</p>
  
  <p>With <code>ido</code> I use the handy <a href="https://github.com/gvalkov/ido-other-window/blob/master/ido-other-window.el" rel="nofollow noreferrer">ido-other-window</a> package to open existing buffers or files in the <code>ido</code> list to new window splits. For example, instead of pressing <code>RET</code> to open in a new window <code>C-2</code> the buffer/file will be opened in a vertical split.</p>
