If you are a GM on any server, live or shard, you can enable the debug mode. On shards you enter /debug, live GMs are always in debug mode I suppose.
While you are in debug you can do fancy things like pressing F12 to make yourself weightless, you can fly all over the place and use the ]*j command, again that is only on shards, live GMs prolly have even more ]* commands.
The thing is, you can enable the debug flag with a usual Memory Editor.
