So good to see the single character keyboard shortcuts from the old Opera, although some functionality is working differently, need to press 1 and 2 twice to switch back and forth? It used to be that 1 and 2 would go to next and prev tab, but now 3 and 4 seem to have been assigned for those. 1 (cycles bt. tabs?), 2, 3 (next tab), 4 (prev tab), z (back), x (forward)
