I had the same problems using both GTK+ 2 and 3 programs. This is a bug in the GTK+ libraries, which has been solved in later versions. See the following commits:
GTK+ 3: http://git.gnome.org/browse/gtk+/commit/?id=314b6abbe8d8daae1e2de50b15cc9b6553af1f3d GTK+ 2: http://git.gnome.org/browse/gtk+/commit/?h=gtk-2-24&id=1533e67ae40d938a6ee805eab5581922f4b97459 Ubuntu 12.10 uses GTK+ versions 2.24 and 3.6, which already include these patches. Please apply these patches to the GTK+ libraries in Ubuntu 12.04, such that GTK+ programs which use shift+function key in their key bindings are useful again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990617 Title: Shift + Fx key combination doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/990617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
