[orca-list] running the live cd

[michael weaver <weavermicha googlemail com>]

how do i run the latest ubuntu karmic live cd with speech?
i have just bought a new desktop pc today and i don't want to 
make any changes to the actual system at present.
it is a compaq desktop i think with windows 7 on it and 4 gig ram 
and it seems to load ubuntu but i am not sure if any of the 
keystrokes have changed for speech accessability.
i can run speech sort of when i leave ubuntu to load but i can 
only get as far as the login sound so i think i need to know the 
keystrokes when the live cd is booting.
