Exiting scrollback mode in byobu
In byobu, I am able to enter scrollback mode with F7. However, I am not able to exit by pressing ESC as documented. Nothing happens when I press ESC. In contrast, when I am in screen, I am able to enter scroll back and exit by pressing ESC. (Oddly, I also can't access scrollback by hitting alt-pgup. Maybe a terminal emulator issue?)
I was able to exit scrollback by pressing ctrl+c or Enter.
Pressing q aborts the mode as well.
Discovered it via tmux man page, but it also works for session backed by screen.
