After I posted a message on GNOME on Google plus https://plus.google.com/+AndrewMillington0/posts/hJaUYZZnLSR The short cuts were disabled and after an update those short cuts were somehow enabled with a single key even though shown as disabled. The keys in question was 's' an 'l'. 's' was allocated to default help and 'l' to the screen keyboard on/off. I spent a bit of time checking if I am doing the right thing in turns of existing bugs and reporting to the right area. lsb_release -rd Description: Ubuntu 16.04 LTS Release: 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-gnome/+bug/1577125/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
