I have just installed Ubuntu 12.04.
At the beginning I used Unity, I downloaded and installed Chrome, Ubuntu tweak (where I configured my favorite shortcuts) and decided to switch to Gnome-classic (Unity was so slow on my machine). Unfortunately in both Firefox and Chrome shortcut Ctrl+T does not work (But others shortcuts work well). Maybe I misassigned it by mistake or there is another magic.
How can I check list of all shortcuts on my system.?
I tried in keyboard settings, gnome advanced settings, dconf editor - no trafe after Ctrl+T.
Is there a way to assigne/force it again?
