How to access nid in views
If you're using the rendered entity style I don't think you can do it through the UI - Views passes off the display to node_view() in that case, and doesn't get involved with the markup for the row.

The easiest way to do what you want is to implement hook_preprocess_node(), look for a View in the current context, and if the node is being rendered as part of that display, you can make some alterations.

For example

function MYMODULE_preprocess_node(&amp;$vars) {
  if (!empty($vars['view']) &amp;&amp; $vars['view']-&gt;view_name == 'foo') {
    $nid = $vars['node']-&gt;nid;
    $vars['extra_link'] = l('Some text', "node/$nid");
  }
}


Then in your node.tpl.php file you'll have access to $extra_link.
