Live.observer properties

Today I feel so retarded.
I’m looking for this everywhere and I didn’t find anything!

Is there a place where I can learn which kind of property I can get using the live.observer object?!
I find just few examples but what I’m looking for is a complete list of properties!
Even on the reference file I didn’t find them. I found it so retarded that I though that probably there is something wrong with me…
