using keyboard (only) to navigate in Web sites

Droid 3 keyboard navigation expert needed:
In using the Droid 3 keyboard to navigate to and within Web sites,what keys should one press?
For a specific example, from the home screen, I can press the down (or up orleft or right) arrrow on the keyboard to get to the browser and, once there,
press the OK key to open the browser,
then I press the magnifying glass key to open the URL bar,
then type in a Web site (such as msn.com),
then the 'return' key; this brings me to the Web site---
but after that, the navigation via keyboard seems to hit a deadend.
I can press the down arrow key, to go down the Web site---
but what about opening up a hot link within the site? How do I do that? I have tried seemingly every key withoutsuccess. For example, at a site like MSNthere are hot links to several stories. How can these be opened using only the keyboard? There must be some key---or combination ofkeys---that would do this.
Maybe someone knows how to do this . . .
