Shortcuts are not working

Issue

I just installed your extension and my first impression is wow!
However, some shortcuts are not working.

Copy

More precisely, the CTRL+SHIFT+C to copy the translated text keeps copying the original text instead of the translated one. I did not look at your code, but you may ensure it takes the right panel text no matter what was the first language used (may produce a bug after language switching).

Toggle transliteration of the result

The TAB shortcut which is supposed to toggle the transliteration of the result has simply no effect.

For me some hotkeys works, but only with English layout. With Russian layout doesn't work anything. Ubuntu GNOME 17.04
