The New Form Controls:
Radio Buttons

The new radio buttons are now enabled (along with checkboxes) in the latest WebKit builds. Radio buttons behave as checkboxes do, meaning that they wont respond to properties like background-image or border until you disable the -webkit-appearance property. Once you do, you’ll get a completely blank slate and can define how all the states of the control should look.

I also did some cleanup on radio buttons to make them more consistent with WinIE and with OS X as far as keyboard navigation goes. The radio group is now a single item as far as tabbing is concerned, and the arrow keys can now be used to navigate within the radio group itself.
