/SET_STATE=state-name
Causes the specified state to be set when you press the defined
key. The state name can be any alphanumeric string (for example,
GOLD). Use the DEFINE/KEY/IF_STATE=state-name command to
associate new meanings for keys when the specified state is set.
See the example for the DEFINE/KEY command.
If you omit the /SET_STATE qualifier, the current state that was
locked remains in effect.
