A Tcl variable is associated with each group to indicate which of the group's buttons is selected.  When the 'Tristate' button is pressed, the radio buttons will display the tri-state mode. Selecting any radio button will return the buttons to their respective on/off state. Click the \"See Variables\" button to see the current values of the variables."
