Weird things started to happen as of this updated. Since that update, visited links worked only once. Links gain :visited style, but it gets completely ignored it seems. Well, most of times at least. Check screenshot

Oh, and it's not limited just to the site on screenshot, it's same for all.

That is because the shortcut for the undo action considered context (what your last action was and where you last clicked in the UI).

So it's planned for the future, right?

They have been reserved for use but we haven't chosen to enable them yet, since we have to deal with folders and we have not decided on how best to manage that.

Oh, hopefully you can enable them soon.

Anyway, thanks for your help.

@ruario, thanks a lot for keybinds. This helps.

And you're right, though in old Opera both could be bound to Ctrl+Z

Also, GoToSpeedDial_1 → GoToSpeedDial_9 do not work. Any idea why?

As you most likely know, you can't easily customize short cuts in Opera and that creates all kinds of difficulties to users who are trying to migrate from old Opera.

Currently, there is way to customize short cuts via file Preferences in Opera\profile\data\ by adding something like

      "Basic": {
                  "ReopenLastClosedTab": [ "Ctrl+Z" ],
                  "SomeAction": [ "SomeCombo" ]
      }

Question is, where can I get list of actions like ReopenLastClosedTab from to re-bind other needed things?
