[noob again]objects and properties and messages

[Mikey]

is there a reasonably comprehensive list somewhere of what properties
and messages are associated with particular objects?  How about which
properties are read-only vs. writable?  I realize that some of this is
available via Transcript, but I'd like to actually have a
reference/cheat sheet to refer to.

Thanks.
noob.
