tmux and nano in console

[mick crane <mick.crane@gmail.com>]

I'm trying to use the console to see if my editing problems go away.
Want to copy lines from one file into another.
Splitting the screen with tmux with the 2 files opened in nano the nano 
buffer is not shared.
Seems can have more than one buffer in nano but the things I want are 
not in the same file.
If use the mouse to select text in one file in one tmux window the 
selection goes across both windows/files.
Is there a way in console to achieve copying lines from one file to 
another ?
