Moving Calendar and FAQ to navtab

[Winzlo]

Has anyone successfully moved the FAQ and Calendar links to the navtab from the Forum navbar? I've made a plugin and transplanted the code from the navbar template, but it seemed to choke on the variable references.

Here are the lines as they appear in the navbar template:

<li><a rel="help" href="faq.php{vb:raw session.sessionurl_q}">{vb:rawphrase faq}</a></li>
<li><a href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>

Here is what I put into the process_templates_complete plugin:

$template_hook['navtab_middle'] .= '<li><a class="navtab" rel="help" href="faq.php{vb:raw session.sessionurl_q}">{vb:rawphrase faq}</a></li>';
$template_hook['navtab_middle'] .= '<li><a class="navtab" href="calendar.php{vb:raw session.sessionurl_q}">{vb:rawphrase calendar}</a></li>';

This resulted in literal translations, as the single-quotes normally do. So, I tried a concatenation variation with no luck:

$template_hook['navtab_middle'] .= '<li><a class="navtab" rel="help" href="faq.php' . {vb:raw session.sessionurl_q} . '">' . {vb:rawphrase faq} . '</a></li>';
$template_hook['navtab_middle'] .= '<li><a class="navtab" href="calendar.php' . {vb:raw session.sessionurl_q} . '">' . {vb:rawphrase calendar} . '</a></li>';

Admitting that I am still a novice in this kind of programming, can someone help point out what I'm doing wrong here? Thanks!
