The HelloCheckBox Sample used for Accessibility/FX testing has one active control, a tri-state checkbox.

At least three controls are needed to exercise and test focus tabbing (TAB and SHIFT-TAB) and other keystroke commands.

For example, a two-state checkbox could be added, and one other control.
