Here is the title in Motion:

Notice there is a "Rig" there. Select the rig and then click +Checkbox to er... add a checkbox:

Now we are going to "rig" some parameters to that checkbox... in this case, all we need to do is turn the visibility of the Background group on and off, as we turn the checkbox on and off.
The checkbox is on, and so is the Background group, so that should be fine. Anyway, we may "record" this setting: press "Start" to start Edit Mode: this is where we'd make changes associated with the current state of the checkbox. In this case, we should just click "Stop Edit Mode", since there is nothing to change.
Next, we set things for when the checkbox is OFF. Turn it off, click "Start", turn the Background group visibility off:

Now we are ready to click Stop Rig Edit Mode, and our checkbox is done.
We just need to Publish it.
Finally, we want to change "Checkbox" to a more descriptive name. Select the Project, and click to edit the name of the checkbox.
