A snippet project showing the problems

Arrow Keys with radio buttons behave differently in RWT and SWT.

1. First discrepancy:
In SWT using arrow keys change the focus but not the selection of buttons
In RWT the arrow keys change both focus and selection state

2. Second discrepancy:
In SWT using arrow keys skip the disabled buttons. In RWT disabled buttons can still be selected.

I attach a snippet project to reproduce the problems

Workaround replacing the default arrow behavior

Here is sample of code to workaround this issue and have a behavior similar to SWT

At least in SWT on Windows, arrow keys change both focus and selection. That's why I think that the RWT behavior is correct. I agree with the second issue - disabled button get selected with arrow keys. Disabled buttons should be skipped instead.
