3 Keys

[Gunther2]

From the moment I get my hands on the Keyring, I put every single key I have on ot. So my question is:

1. The key that you nick from Selina is usable much later in the game, but what can be opened with it?
2. There's a yellow key on top of Torrissio's fireplace. What can be opened with that (it's not the chest in his room, since I opened that one with some lockpicks)?
3. Inside Frigidazzi's drawers where your Magic Helm is, is also a Blue Key, what can be opened with that one?

i think that key 2 opens a door in the woods. But if you did not play it before, it would be a spoiler...

Actually I have, but I always put my keys on the keyring, so I don't know what opens what. And Kikoskia's walkthrough wasn't really helpful when I checked it to see if he found out what those keys open, since he put them all on the keyring aswell from the moment he got it.

And I think you're confusing that one with the one in Stefano's place, which is a dark green key.
