Fokus for Opera

From original author of Fokus: "Fokus uses JavaScript to emphasize anything you select by covering the rest of the page with semi-transparent black."

See http://lab.hakim.se/fokus/ for the original scripts.

This extension also includes an options page to change opacity and padding between highlighted area and dark background.

*** About context menu ***
I have also noticed that selected text can't be copied using context menu but it's a bug of the original script and not of the extension.

As long as the original author does not fix it, consider this as a feature and not a bug.
