_Dbg_help_add frame \
'**frame** [*frame-number*].
Change the current frame to frame *frame-numbrer* if specified, or the
most-recent frame, 0, if no frame number specified.
A negative number indicates the position from the other or
least-recently-entered end. So **frame -1** moves to the oldest frame.
