The script defines a couple of aliases for your usage :

• MMset : this is the wrapper around mastermode, it will automatically grab master for you if required.
• MMiam : tell the script what your clientnum is - currently only MMallspec uses it, though
• MMallspec : send everybody to SPECTATOR, for when they're just asking for a time-out...
• MMgriefkick : kick everybody [thanks to Script Kid for this one]

It will also output some (hopefully) useful text via chat,
to inform the other players of who's in control ;-)

The default bindings set by the script are :

• RETURN : MMset 0 :: grab master
• V : MMset 1 :: veto
• PAUSE : MMallspec :: Time-Out
