selects controls to be modified
turns selected controls on (1) or off (0)

XkbSetXlibControls modifies the state of the controls selected by bits_to_change; only the controls selected by bits_to_change are modified. If the bit corresponding to a control is on in bits_to_change and also on in values_for_bits, the control is enabled. If the bit corresponding to a control is on in bits_to_change but off in values_for_bits, the control is disabled. bits_to_change should be an inclusive OR of bits from Table 1.
