Opera ships with multiple keyboard shortcut profiles. Where is the Firefox-compatible profile?
Opera tends to open a mail client setup dialog when I try to search, and to do nothing when I try to switch tabs. This keeps interrupting what I'm trying to do, and I'd rather not retrain my muscle memory. Chrome has been much more convenient to use, keeping the usual shortcuts working (exceptions: Ctrl-Tab in MRU order, F6 which I'd expect to cycle between major ui areas).
While there's a lot that does work (such as Ctrl-LDJBS), I'd like the following to be ported: Ctrl-K then Alt-Enter, Ctrl-L then Alt-Enter, F6, Ctrl-PageUp/PageDown, Ctrl-Shift-PageUp/PageDown.
