I've just migrated to a new computer and am using 54.0. The ctrl-space key now loads a pop-up window to "search for open tabs." On my old computer (53.0) the same key combination brought me to the speed dial. Is there any way to change this or at least create a key-stroke combination to go to the speed dial?

In Opera 12 there was a nice security feature, a master password that could be set asking a user to periodically give that before any stored passwords could be used. I cannot find this feature in Opera 18. Is it somewhere that I can't find? If not, would it be possible to resurrect this feature?
