Menu
Usually tmux will only show as much output as however many rows my terminal currently displays. And then when I detach it, it clears all of its content. I know how to look at scrollback (ctrl+A, [, k, ...), but how can I configure tmux to just print all its output to terminal, as if I wasn't using it at all?
I like tmux because I'm awful at remembering to nohup certain tasks, and because it makes viewing the output of long-running jobs easier. But I would like to be able to view its scrollback more naturally, by simply scrolling back in iTerm2.
Alternatively, if there's a way to do this in screen, I can use that too.

Enable and Use the Scroll Mode of Tmux When a user is done with scrolling, he can get out of scroll mode in Tmux by pressing the Q key. If that did not work as per the expectations, then check if using the F7 key to enter the scroll mode and q to quit the mode solves the problem.
The first key combination (ctrl+b) puts tmux into command mode. The percent tells tmux to split the window vertically. Even moving between the vertical panes takes two keyboard interactions. The first is ctrl+b which puts tmux into command mode.
In order to save an entire tmux session, type prefix + Control + s .
I use bash, so ctrl-l already does the equivalent of typing "clear" at the command line. With these two keys I get a nice ctrl-l, ctrl-k combo, which moves all the scroll buffer off the screen (the "clear") and then deletes all that history (the tmux "clear-history" command).
iTerm2 build 1.0.0.20130302 has an preference which enables it to capture scrollback even when a so-called hard status line is present:
Works for me, tested with tmux v1.8.
