Description of problem: I realize keyboard traversal is not an overriding 
design goal for many GUI pages -- but a lot of good work _has_ been done and 
there's currently a glitch in the keyboard traversal mechanism on the page 
where on enters their RHN user name, password, etc.

If you press TAB repeatedly to move the "Enter-key target" from one widget to 
another... all the widgets _except_ the "Forward" key are eventually selected.
It seems the Forward key isn't in the list of widgets to traverse.

Version-Release number of selected component (if applicable):
8.0 firstboot

How reproducible: 100% (always)

Steps to Reproduce:
1. Install 8.0
2. reboot into firstboot
3. say "yes" to "register with RHN?"
4. on the page with username, password, etc., traverse the widgets using the 
TAB key
5. notice that the Forward button is never highlighted/selected.
