+### Change how to open new files
+
+By default when following a link the target file will be opened in your current buffer.  This behavior can change if you prefer using splits or tabs by using the `vim_markdown_edit_url_in` variable.  Possible values are `tab`, `vsplit`, `hsplit`, `current` opening in a new tab, vertical split, horizontal split, and current buffer respectively.  Defaults to current buffer if not set:
+
+```vim
+let g:vim_markdown_edit_url_in = 'tab'
+```
