navigating links with safari.

[Clinton Waterbury]

Hi all, just had a question about navigating links on safari.  While I was at 
the Apple Store in Salt lake city checking into the macbook air, I figured I'd 
check out the newest version of mac and see what they had changed with 
voiceover, but when going into safari I found I wasn't sure how to navigate 
links, but could load other sites.
If anyone has info on a certain command for it, it would be vary much 
appriciated!
