Actually back in Opera 5 or 6 or thereabouts I could set Opera to open in new tab only when I said so myself no matter what the html said, so 12 is less good than older versions, but still a lot better than 24.
Actually, you could do that in 12, in opera:config
4 The ability to ctrl-tab in most recently used order. It's the only reasonable way to do it, but now no browser does it that way. Alt-tab still works in most recently used order.
That's pretty well hidden.
5 F2 for mouse-free entering of URL. It's not as big as the others, but I still miss it.
Don't know if it's what you want but F8 selects the address.
Yes, that's a good alternative. Thank you.
