serverconnection.chasecam(9999999999); places your third person camera in a fixed position for the time specified in milliseconds, allowing you to move about as if someone else was filming you. It's really useful for creating videos.
EDIT: Typing steamGreenLightGui.clickForwa rd(); into the console grants you the ability to use the /greenlight anywhere you want, giving you a green light that most players don't know of.
