Where are 1 & 2 kb shortcuts?

It used to be that in Opera you could use 1 and 2 for going forward a 
tab or backward a tab.  Very handy for scrolling through multiple tabs.  
Either I'm losing it or it appears that they have eliminated this in the 
latest version.  (It was even better to replace 1 and 2 with F (for 
Forward) and R (for Rearward): far easier to reach accurately.)
