Determining the “current_page” in WordPress Custom Menus

Question

I am using WordPress Custom Menus. I have links like

• Home - Rendered using home.php
• Blog - Rendered using page-blog.php with WP_Query to get blog posts
• Services - Page
• Portfolio - Rendered using page-portfolio.php to get all posts of the Custom Post Type "Portfolio"
• Contact - Page

I will like to determine which link is current and style them. How will I do that? WordPress wont know which is selected when I am in a simple blog post for example single.php
