Hi

I am using SLIME to connect to a remote lisp process (running in detachtty) and I am wondering how can quickly jump to a function definition (pressing alt . ). Currently when I press alt . I jump to an empty buffer.
How can I build a tags file for a remote project (if it's possible)?
I was trying to use SLIME's cross reference from the menu. When I point at the function and say for instance "who calls" emacs says "Unresolved, file unknown". I wonder what I am missing here?

Thank you,
Andrew
