I usually browse with multiple Opera windows, each with multiple tabs. On Windows, I can close a single Opera window and all its tabs with ALT - F4. Is there an equivalent keyboard shortcut for Opera on OS X?
I'm looking for something between command - w (which closes only a single Opera tab) and command - q (which closes all Opera windows). Clicking the red "close" orb gets the results I want, but I'm looking for a keyboard shortcut.
