Re: [orca-list] Pre-testing of Orca with Chromium/Chrome

[Peter Vágner <pvagner pvagner tk>]

Hello all,



I am testing all this just now after a little delay and I have to say 
it's impressive.

It's really working great over here.

Minor anojance I have found and needs more testing is that when using 
right and left arrow keys to expand / collapse an aria tree view arrow 
keys are not passed through to the app.

I have experienced this with web.skype.com and with riot.im .

In Firefox this is working as expected.

So in the mean time I'll try to find a generic aria tree example we can 
use to demonstrate this behaviour and try to find out if this is a 
chromium issue or how to improve it.


Also I have put down a few simple steps on how to get the latest 
chromium running on Arch linux and other similar distros.

Greetings


Peter
