I like 'view', the docs could read:

    View a frame that is not part of GDB backtrace.  The frame viewed
    has stack address @var{stack-addr}, and optionally, a program
    counter address of @var{pc-addr}.

    This is useful mainly if the chaining of stack frames has been
    damaged by a bug, making it impossible for @value{GDBN} to assign
    numbers properly to all frames.  In addition, this can be useful
    when your program has multiple stacks and switches between them.

Eli, how does this sound?

Thanks,
Andrew
