What do the cabin symbols mean when travelling Norwegian Cruise Lines?

When I bring up a map of the Norwegian Jade all the cabins have some sort of symbol in them, triangles etc. I know, in general, the symbols mean quad room, obstructed view etc. But with Norwegian Cruise Lines what do the symbols mean? I have found no help on the various travel sites nor from the cruise ship site itself.

maybe go back to caving

Square = disability cabin (ADA)
Circle = hearing impaired
<--> = connected staterooms
White triangle = king sized bed
Diamond = queen bed
Filled triangle: space for a 3rd person
Plus: space for a 3rd and 4th person
White star: up to 6 people
Filled star: up to 5 people
O = "family friendly accommodations"

You have to roll the mouse over the legend in the bottom right hand corner:
