Hi, @Joel: If one has order_statistics_tree<string, less<string> > with string values and less comparator, and the container has been inserted: cat, dog, bird, fish, dinosaur then the elements can by accessed by ranks of the keys in that container. In example tree[0] returns bird while bird is the least element, tree[1] = cat, tree[2] = dinosaur, tree[3] = dog, tree[4] = fish, which is the greatest.

Briefly, it is container which allows logarithmic inserting, searching and erasing as in set, but additionally it permits to access elements via numerical value - key order.
Can you clarify what you call key order? Maybe some examples?
