[MlMt] Opening a mailbox from "Go to Mailbox..." in a new viewer

[Sherif Soliman]

Hi all,

I don't recall if this has ever been mentioned or discussed on the list 
before.

Is there a way to use the "Go To Mailbox..." dialog except open the 
mailbox in a new viewer?
I tried a couple of modifier keys but it always opened the mailbox in 
the same viewer.

If that cannot be done right now, it would be pretty neat if it was 
implemented in the future (say, type few letters, get the mailbox you 
want highlighted, and have the mailbox open in a new viewer if you use 
the ⌘ modifier with the Enter key).
