Hi Yuki, do you think you could tackle this one? Maybe you can hook up the actions in our idl's and if you'd like, hook up a new actions menu in the ChromeVox Panel. I can do the latter if this sounds like too much.

Yes. Which is the targeted milestone? Is M60 okay? I won't be able to immediately start working on this item.

m60 sounds great!

My plan is to add a new top level item "custom actions" in ChromeVox panel, and add custom actions there. We might be able to assign new keyboard shortcut to open the menu quickly.

David, WDYT?

I believe this is done; re-open if there's anything remaining.
