displaying the same content in both panels

[root <lojurk inetia pl>]

Hi, list!!!

I'd like to know if there is any way of displaying the same contents in
left and right panel. I am in the left one  and want to have the same in
the right one. I was wondering too how to make shortcuts to frequently
used directories. And the last one how to display info???
Thank you all for help.
