Melodyne (ARA) keyboard shortcut question

[gdgross]

Happy Friday all,

So twice now, while working in the new ARA melodyne implementation, I have inadvertently pressed some key or key combination on my keyboard, which I can only assume is a death-to-everything/delete all shortcut.

It's deleted the melodyne from the track I was working on, and make it look like I'd never implemented it at all. Lost half an hour or more worth of edits in both cases, CRTL-Z doesn't bring anything back. In both cases I just opened the last backup and kept working, so I didn't actually lose much, but it's annoying.

Anyone have any ideas what I'm accidentally doing here, so I can avoid it in future??

Thanks
