[PD] Where is the object reference documentation?

[Jim Aikin]

Now that I have real-time MIDI working, I'm eager to start putting 
together the patch I need. But ... where is the documentation that lists 
the available objects? Once I know what object I want, I can create it 
and then right-click on it to open an information window for that type 
of object. But where's the complete list of objects?
