panel switch (Alt-F1 and Alt-F2 in the other OS)

[Zeljko Jelaca <zeljko jelaca com>]

How do I change listing panel in the midnight commander so that the 
panel contents are set to the parent panel?

Like this:

RIGHT PANEL..............LEFT PANEL
/home/user............../src/

Now what key I press to get: Right panel = Left panel?
Like this:

RIGHT PANEL..............LEFT PANEL
/home/user............../home/user

Ps.
No, its isn't C-U or C-o that I'm looking for :-)
