“ctrl+alt+p” stopped working
This is either because the extension has not loaded correctly or because something else is using that keyboard shortcut. If it is the former, you can manually reload the extension by going to More tools --> Extensions, in the Chrome menu Switch the Paperpile extension off, then on again, then reload your Docs tab.
If it is because another application or extension has taken the shortcut, then you would have to check your recently installed/updated extensions and applications for the culprit.
ok, thanks!
