"TAGS" are action commands that tell when an action starts and stops.  At the beginning of your command you will use an "opening tag."  At the end of your command you will use a "closing tag."  The opening tag is two brackets with the command inside [  ] .  The closing tag comes at the end and is also two brackets but contains a foward slash, as well [/  ] .  Only what is in-between the opening and the closing tag will be affected by the command.
