how to paste from byobu's screen buffer (ubuntu 12.04 64bit)

I'm running byobu in gnome-terminal, under ubuntu 12.04 64bit. and trying to copy a screen buffer.

i.e. by hitting F7, byobu entering "copy mode", then mark screen text by space key.

the question is, how to paste those text after it copied those text into it's screen buffer?

in case anyone need the answer, after google around, I found the solution below.

the short answer is : ctrl-A ]

A longer answer: to save the text into a file, open a text editor, such as vim, set it to paste mode ( :set paste ), then input mode ( i ), then paste it from byobu: ctrl-A ] done!

After the Enter, press Alt+Insert.
