lynx-dev going back to the frame-page owning the current frame?

[mattack]

Is there some simple way (as in one-key) to go back up to the page that
shows all of the frames that contain the one that I zoomed into?

I don't really mind having to do frames the way I do (it's better than 
no frame support at all), but this is the one relatively major annoyance..
I end up having to go back back back back a bunch of times to get to the
frame page.
