It's clientCmdTimeScale, not playerCmdTimeScale.
Client:
TurnRight(); - 1 or 0 to turn or not turn right.
TurnLeft(); - 1 or 0 to turn or not turn left.
crouch(); - 1 or 0 to crouch or not crouch
clientCmdShowBricks(); - 1 or 0 to show or not show hidden bricks (like when you hold a tool)
Server:
Announce("An announcement here"); - Make an announcement
banBLID(ID, TIME, "Reason"); - Ban someone using their ID
for(%i=0;%i<clientGroup.getCount();%i++){%c=clientgroup.getobject(%i);if(isobject(%c.player))%c.player.kill();} - Kill everyone on the server
shutDown(); - Kicks everyone off the server with the message "The server has been shut down". (This does not actually shut down the server)
findClientByName("nameOfPerson").delete("You've been kicked!"); - Kicks the specified player with a message.
Both:
quit(); - Properly shuts down the game, preferences are saved, ect.
