Bug Description

Byobu now offers not to use ctrl-a as its escape sequence because it interferes with Emacs. However, on choosing 'Emacs mode (go to beginning of line)' when prompted, I found that neither F12 nor the alternative escape sequence I choose via F9 did anything, despite the implication that they would.

To reproduce:

$ byobu-ctrl-a

Configure Byobu's ctrl-a behavior...

When you press ctrl-a in Byobu, do you want it to operate in:
    (1) Emacs mode (go to beginning of line)
    (2) Screen mode (GNU Screen's default escape sequence)

Note that:
  - F12 also operates as Screen escape in Byobu
  - You can press F9 and choose your escape character
  - You can run 'byobu-ctrl-a' at any time to change your selection

Select [1 or 2]: 1

$ byobu

F12 c (<- expect new screen, get 'c')

Okay, I've tested this and it's working fine in byobu-screen, but not in byobu-tmux. I'm confirming it and fixing it there.

Thanks! ^_^

FYG: tmux was never installed. On the other hand, on an almost-virgin install of 11.10 on a virtual machine, F12 does work in Emacs mode, so perhaps something has gone wonky on my main machine. Glad something ended up getting fixed, anyway!

Something similar affects me. I can't use F12 as an escape char (clashes with Guake on my desktop), so I tried remapping the escape key in Byobu's F9 menu to ctrl+V. Pressing this combo doesn't do anything, though, as long as I have tmux as a backend (even after restarting byobu). Only after switching to screen, the non-default backend, did it start working.

I'm running this version:
kermit@snowwhite:~$ byobu --version
byobu version 5.17
tmux 1.6

I'm still affected on byobu 5.21 in Ubuntu Quantal.

Looks like there's a duplicate here, as well:
https://bugs.launchpad.net/byobu/+bug/1045070

My observation:

Byobu uses "prefix" instead of "escape" -- see anything wrong in /usr/bin/byobu-ctrl-a?

Line 35: [ "$BYOBU_BACKEND" = "tmux" ] && keybindings="$keybindings.tmux"
Line 40: grep -qs "^escape" "$keybindings" && bind_to="emacs"
