In Opera 11, how can I set up shortcuts to switch to specific tabs?

In Firefox on Linux, we can use Alt+1, Alt+2, etc. to switch to the first, second, etc. tabs, till the 9th tab. This is very useful to switch between tabs. In Opera 11 on Linux, I couldn't find a way to do this: the only way to switch among tabs seems to be to use Ctrl+Tab and then cycle till we reach the tab that we want. Needless to say, this "linear access" method is slower (and more annoying) than the random access available in FF. So my question is:

How can I set up shortcuts in Opera 11 on Linux so that I can switch to one of the first nine tabs using a numbered shortcut?

There doesn't appear to be a way, at least it's not listed on their shortcuts page and I didn't find a way to do it. Though you can customize shortcuts, you can't add new actions and there aren't any actions for visiting tabs 1-9. I customized Opera to use Ctrl-PageUp/PageDown to go to the previous/next tab, but it's not as fast as going directly to a tab.

Well here's the right answer; we're lucky, it came out on june 1st. Also, here is the list of all of Opera's Actions commands, but i could'nt figure that one out...

Preferences (Ctrl+F12) > Advanced tab > Shortcuts > Edit {a duplicate of Opera Standard preferably} > Application > New... > {choose shortcut like: w alt} > Actions :: Show popup menu, "Internal Window List"

Opera users should have these two sites bookmarked.
