Hi CDX,
Thanks for writing. There is a simple solution to problem #1. Go to Advanced Options. Create a a new account and in the field When URL Contains type msn.com. In the Use this URL field type passport.net. Now the same password is generated for both msn.com and passport.net.
For problem #2, actually the shortcut isn't cntrl+, it's cntrl+` (cntrl plus tick). On many keyboards, the tick-mark is located just above the tab key.
