I use byobu with the tmux backend on my 12.04 server. I'd like to use the midnight commander shortcut keys with it, but the F keys don't work.

I've seen some posts on the issues here:

but they are out of date and don't seem to work for newer versions of byobu. How can I either work around this or use MC in a way that works better?

Same goes for htop and others. –  jrg Jun 5 '12 at 3:34

You can easily toggle on/off the use of the F-keys inside of Byobu (tmux) by pressing either:

  • shift-F12 (in tmux)

  • ctrl-a-! (in screen)

Full disclosure: I'm the author and maintainer of Byobu.

How do you make it off by default, and turn it on as needed? @Dustin-Kirkland –  Pykler Nov 6 at 20:52
    
Got it, add source $BYOBU_PREFIX/share/byobu/keybindings/f-keys.tmux.disable to your .byobu/keybindings.tmux at the end –  Pykler Nov 6 at 20:59

Hah, a man after my own heart :)

Short answer: add my ppa (ppa:izx/private) and update byobu (or manually install the deb). Byobu will default to screen as the backend with F-key behavior restored to old 4.x style.

Long answer: Use byobu-select-backend to switch to screen if you haven't already, and add line $BYOBU_PREFIX/share/byobu/keybindings/f-keys.screen.disable after the line $BYOBU_PREFIX/share/byobu/keybindings/f-keys.screen in /usr/share/byobu/keybindings/common.

But what if we wanted to keep it with tmux? –  jrg Jun 5 '12 at 3:34
    
@jrg: I'm not that familiar with tmux, sorry -- I tried the new byobu but after this now-fixed bug, switched back to the screen-backend because I'm used to it and happy with it, whatever its limitations. –  izx Jun 5 '12 at 4:37

To trigger F-key press ESC,2 (one after another) instead of F2. Feels more convenient than switching using:

shift-F12 (in tmux)

ctrl-a-! (in screen)
