Top Sites in Safari

Hi all, I'm new to the Mac world. I have been a PC user since 1994 when I first learnt how to use one, I was about 8/9. Now I'm 24, and purchased my first MacBook Pro 13'.

How can I navigate through the web pages that appear in the Top Sites section, using the keyboard. I have tried using the arrow keys, but nothing happens. However I can navigate through the History using the arrow keys.

Any ideas?

Thanks in advance

I would seem that it is impossible to navigate top sites with a keyboard.
Why I don't know, maybe because apple thought more along the lines of a speed dial on which you have to click.

You can request that it be added here, but don't hold your breath.
