I found the "Keybindings" in opera.pak, but it seems this combination is not bound to what i would expect.
The following binding is set: "PastePassword": ["Enter+Ctrl"],
But one question:
If you're entering text right here in this forum, and then press "CTRL + Enter", does it save the entered text or does it refresh the page?
On my opera, it only refreshes the page.
