Using Keychain to find a password
I've tried to rescue a password using Keychain Access, but it's confused. If I click in Passwords in the left column, appears many options in the right, but it's not very clear. How do I find a specific password, let's say, my iTunes Store password, or my Gmail email password? There is several options and it's confuse.
