What are the volume key mapping commands?

[Lend27]

I installed LL2.6 beta on my Chromebook Acer C720.
All is well except a few issues.
I am trying to map the volume up, down, and mute keys to the volume keys on my keyboard.
What commands would I use?

Thanks!

Hi Len, not many people using LL on a Chromebook as reported, so it's difficult to support properly. Have a look through here - https://github.com/dnschneid/crouton/wiki/Keyboard see if it helps.
