[orca-list] maybe off topic: using chromium and chromium-chromevox

[Al Sten-Clanton <albert e sten_clanton verizon net>]

Greetings!  I've sent this message to another list.  I send it here in 
case there is supposed to be some interplay between Orca and chromium 
accessibility.
I'm seeking to take a Linux system administration course offered by the 
Linux Foundation, a course that ends in an exam.  The short story is 
that apparently I need to use chrome to take that exam.  Well, Arch 
Linux does not seem to have chrome available but does have chromium, 
which I gather is a close sibling to chrome.  Arch also has 
chromium-chromevox (in AUR), which is supposed to force chromium to use 
a screen reader.  I hope I'm not oversimplifying, but this is my 
understanding.
Having installed chromium and then chromium-chromevox, then reinstalling 
chromium for good measure, I tried running chromium.  I've gotten 
nothing but the occasional tone or group of tones, and I'm not sure what 
caused them.  I've had orca on and off.  I tried keystrokes noted in the 
user guide at www.chromevox.com, such as tab or combining control or alt 
with an arrow key, and have gotten nothing.
Does anybody have any suggestions?  Am I stumbling down the wrong rocky 
path?  Thanks for any help.
Al
