How can I change the title tag in header of just one page? I tried Page Title module however it seems that it can configure page titles only on the content type level. 

I can make a temple for this page and write the title directly in there but I don't feel like overriding the template file just for the title tag.

Is there any other way to set the title to just one specific page (node view page)?
You can manage this in template.php file.

function MYTHEMENAME_preprocess_page(&amp;$vars) {
    $vars['title'] = $custom_title;
    $vars['head_title'] = $custom_title;
}


Just put the condition in the page like for specific path, content type etc. and change the title of the page.

function mytheme_preprocess_page(&amp;$vars){
    if (isset($vars['node']) &amp;&amp; $vars['node']-&gt;type == 'news'){
        drupal_set_title('News');
    }
}
