Materials Lists Calculate by Room VS Area

[Ezevans]

I would think calculate by room would use the name of the room and calculate by area would use a curser selection for creating a material list, however they both seem to be exactly the same. They both use a cursor selection to define the area you are trying to generate the list for.  Am I missing something?

From the software's Help:

"A Materials List calculated from a room is created for only the contents of that room: wall materials are not included."
