DoorKeeper Moniker

A Moniker is a name for something, in this case a door. DoorKeeper uses a moniker to display the door ID along with other information as required.

Suppose the door ID is a number, such as 101. Successive doors may have their ID incremented to 102, 103, etc. If you want the moniker to display just that door ID, then you can instruct that to appear using a basic expression. You may want to prefix the ID with D for door, which needs a trivially more complex expression.
