What are the keyboard shortcuts for copying login and password in 1Password without using the browser extension?

Question

I am using 1Password (version 3.8.5) to manage my login data and somehow I am reluctant to use the browser extensions. I want to speed up my login and password acquisition though and therefore I am searching for keyboard shortcuts to:

1. Copy a password
2. Copy a login

The keyboard shortcuts for getting to the login I have searched for or for tabbing to the correct item in the UI is something I am already familiar with.
