Sorry, I forgot that the psoting software would remove brackets (and text within them)... I meant to include the actual shortcuts: (CTRL+Enter) to tab between Opera tabs, (ALT+Enter) to switch applications under MS Windows.
And ALT+TAB to switch between any apps including browser sessions. Tabbed browsing is a feature, no doubt, but I like my browswer window as big as possible and IMO it just eats that precious space. Can you turn it completely off, if you want? I would hope so, surely possible. Still just an inconvenience, IMO.
