Any keyboard shortcut plugin working in Roundcube 1.6.1?

[necrevistonnezr]

None of the "keyboard_shortcuts" plugins (see https://github.com/corbosman/keyboard_shortcuts/network/members) work anymore after updating to Roundcube 1.6.1.
Other plugins are fine - but if I activate this one, Roundcube doesn't load anymore.
I had last used https://github.com/texxasrulez/roundcube-plugin-keyboard_shortcuts

EDIT: https://github.com/random-cuber/hotkeys doesn't break Roundcube, but doesn't really work either, e.g. it does not have a "mark as read" shortcut and the whole setting page looks weird...
