[orca-list] Is there a standard guide for using gnome keyboard only?

Hello, is there a standard guide for using gnome with just the keyboard?  I've figured out most things.  
I cannot seem to get a few though.

How does one access the "system tray" area?  That is the place with the little deamon icons...

How does one access the window options menu?  That is the one with the "Minimise, maximize, move, change 
size" ect(hope I got those correct, I'm translating from Czech here).

What kind of method does orca provide for blind people to "discover" objects which they cannot see and do not 
know how to move to?  In using orca, it will read me the time, but I have yet to find a way for it to tell me 
what is IN the system tray, if that makes sense.
