Yes.  They're roughly analogous to directories (keys) and files
(values).  Each key has a default value, can have multiple values and
can have multiple sub-keys as well.  To make things more complicated,
you can have a key and a value with the same name (I just tested it).  :-)

When you use the registry from a program, you open a key and can then
get a value or enumerate its sub-keys or values (two separate functions).
