keystrokes for running Orca in ubuntu

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

When I try to boot Ubuntu with speech on the Ubuntu desktop CD I notice 
that I seem to get magnifyer as well.
I have been having a look at the Feisty CD and it seems to work better 
on my desktop than the Live CD for Edgy although it does take a few 
attempts to start speech but I am wondering if the problem is that I am 
using too much memory on something I don't use because when Feisty runs 
as Live from the desktop CD I hear something about magnifyer.
What I do when I try to boot the CD is press F5 followed by 3 and enter 
twice when I hear the beep through the speaker of my Desktop but I am 
wondering if 3 is speech and magnifyer as I don't get speech until I do 
alt F2 inside Ubuntu so I am wondering if the accessibility options for 
just speech are different or when you select speech you have to run the 
magnifyer as well.
Perhaps someone can tell me.
Unlike Edgy I do seem to be able to get into a terminal and I have 
managed to run W3m although I don't know the keystrokes for navigating 
through forms as tab doesn't seem to take you through links and leaving 
one field and going to another with the down cursor doesn't respond.
