d3zorg / fix for hotkeys not functional in non-latin keyboard layout in 13.10 and 14.04
Created May 30, 2014 10:42
fix for hotkeys not functional in non-latin keyboard layout in 13.10 / 14.04
tested on ubuntu 14.04, jvm7 and rubymine 6.3
sudo add-apt-repository ppa:attente/java-non-latin-shortcuts
sudo apt-get update
sudo apt-get dist-upgrade
restart unity-settings-daemon
now ctrl+c, ctrl-v etc should work in most java applications like IDEA, RubyMine IDE even on russian keyboard layout
