The list of earcon sounds in the tutorial should be equalized. Some only play from the right ear speaker, although they are actually on the left side of the screen. I only had one headphone earbud in when going through this, so I just thought the sounds weren't working for some of these list items. We should look into equalizing this. 

I'd also love to see this list of sounds available in a standalone page (or have a shortcut that opens you directly to this page in the tutorial, like Search+O+E, to reference the earcon list at any time. We've received this request for an earcon guide in the past, so this could be a simple way to achieve having a guide of sorts.
