Disable keybindings in byobu using tmux backend

Solution 1:

You're so close! You're just missing the capitalization of "R" in M-Right and "L" in M-Left.

Just add the following to ~/.byobu/keybindings.tmux:

unbind -n M-Right
unbind -n M-Left

And then press F5 to reload your profile.

Full Disclosure: I am the author and maintainer of Byobu.

Solution 2:

If you cannot manage to disable specific keybindings, you can toggle Byobu's keybindings off/on using Shift+F12 – which is what I use a lot (e.g. to interact with Midnight Commander). I just miss a possibility to have the current status of that displayed in the status bar (are keybindings currently active – or have I turned them off?) – but that's a different issue ;)
