One of the best things about byobu is the scrollback feature in a given session.

I have been working on something, and I have tons of lines in the current scrollback session and I want to copy everything to a file, how to??

According to the screen home page, looks like you can do this? but when I'm done I do a search for all those files, can't find them.

   C-a h       (hardcopy)    Write a hardcopy of the current window to the
                             file "hardcopy.n".

   C-a H       (log)         Begins/ends logging of the current window  to
                             the file "screenlog.n".

For the screen commands to work, I have to be in screen mode, I believe, and not sure how to check that?

This is from the byoby man page and I absolutely don't know what it does? I tried, it, and looked around, can't tell.

Ctrl-a ~ - Save the current window's scrollback buffer

there's also enter, copy mode, select with space key, and press enter to copy, I do that, the screen displays gibberish for 10 seconds refreshes, done.

cat >> ~/log.output << COMM
--paste using ctrl a ] I think--  
COMM

this confirms the copy paste works, but when I press enter, nothing get saved to that log file, I've checked, I do have write privileges in my home directory. lol

the select all, from the xfce4-terminal doesn't go far enough, and scrolling back with the mouse, well won't work, no need to try it, I know byobu buffer doesn't work like that.
