@rafaeljvieira Thanks for mentioning StartHQ. I should mention that we're happy to bump up the priority of keyboard shortcuts if we get more votes on UserVoice: http://starthq.uservoice.com/forums/198432-roadmap/suggestions/4194272-keyboard-shortcuts

Also, given we support earlier versions of Opera, we would be keen to add support for version 12 as well if we get enough interest from the community.
