Comment 1 for bug 1812414

I came across this while working on some other things related to shortcuts, and I agree it would be nice. I've done a quick patch using Alt+Shift+Q as the shortcut. I checked OS, browser, and screen reader keyboard shortcuts for conflicts and didn't find any.

However, I think this needs some discussion. Do we want to throw in a confirmation dialog, in case of accidents?
