If you like to use the Opera 7.x Navigation bar include the following lines in your /ubbthreads/includes/header-insert.php file:
<link rel="home" title="home:Sitename" href="/"><br /><link rel="index" title="Board Index" href="/ubbthreads/categories.php/Cat/0"><br /><link rel="contents" title="Content" href="/"><br /><link rel="search" title="Board Search" href="/ubbthreads/search.php?Cat=0"><br /><link rel="help" title="FAQ" href="/ubbthreads/faq.php?Cat=0"><br /><link rel="copyright" title="Copyright Title" href="/ubbthreads/viewprivacy.php"><br /><link rel="author" title="Contact" href="/ubbthreads/contactus.php?Cat="><br /><link rel="alternate" type="application/rss+xml" title="last 10 Clan News" href="/ubbthreads/ContentIslands/2_rss20.xml" />
This is just an example and need modification to fit your site. If anyone find a useful action for all other shortcuts (first, next ...) please post it here.
