- Add the Forget button to the toolbar.
- Press the Forget button.
- Try to get to the timespan radio buttons with the keyboard (tab or up/down arrow keys).
- Expected: You should be able to get to them with the tab key at least.
- Actual: They are not reachable with either the tab key or the up and down arrow keys.
The tab key should definitely reach the radiogroup.
The behaviour regarding the up/down arrow keys is less clear. They're sort of like buttons, but the problem is that up/down arrow keys do normally adjust the value like they would in a menulist. We don't want users accidentally adjusting the value as they try to navigate, but nor do we want users being confused by the inability to adjust the value when they do want to adjust it.
Given this, I think we should treat radiogroups like we do menulists; i.e. they should be reachable with tab only and up/down arrow keys should be passed through when the control is focused.
