Magento: custom titile for any page

1- In page app/design/frontend/rwd/default/template/page/html/head.phtml template replace default:

<title><?php echo $this->getTitle() ?></title>

with this

<title>
   <?php echo ($this->getForcedTitle()) ? Mage::getStoreConfig('design/head/title_prefix').' '.$this->getForcedTitle().' '.Mage::getStoreConfig('design/head/title_suffix') : $this->getTitle() ?>
</title>

or if you don’t wish to use title prefix/sufix added from Magento admin, simply with

<title>
   <?php echo ($this->getForcedTitle()) ? $this->getForcedTitle() : $this->getTitle() ?>
</title>

And now just set “forced” title for pages through layout files Example for My Account page in layout/customer.xml:

<customer_account>
   <reference name="head">
     <action method=”setForcedTitle”><title>Account Dashboard</title></action>
   </reference>
…
</customer_account>
