Some terminal shortcuts don't work within byobu-tmux

I'm not sure if this is a bug or a design decision ... please set importants and assign/unassign as appropriate

I can't actually reproduce this. ctrl-e works just fine. ctrl-a is intercepted because it is the escape code, but 'ctrl-a' followed by 'a' does what it should (act like ctrl-a). Note you can change the escape code by hitting 'f9' and choosing 'change escape sequence'.

This does seem like a regression from the screen flavor of byobu, which
would pop up a question "do you want ctrl-A to be the escape code or
use f12?". Perhaps that was just a transitional thing, and I found it
rather offputting to be asked actually (I'd prefer that the esc code
just be f12 since f-keys are meant for terminal/application control).

Anyway, I think this just needs to be well documented. It would be
especially helpful if byobu changed something on the status line to
inform people that the escape key had been pressed.

Some users tell me that they don't have an F12 key on their keyboard,
Clint. I've never encountered such a keyboard, personally, but that's
what they tell me...

The first-time-you-press-ctrl-a thing is meant to be pretty permanent,
I'm afraid, Clint. You'll be asked the question in byobu tmux or
screen. You have the option of choosing to have ctrl-a behave in GNU
Screen mode, or behave in GNU Emacs mode (and F12 becomes your
escape).

Unfortunately, I don't think that the status line refreshes fast
enough for this to be useful. It refreshes about once-per-second,
which is eons in the scope of keypresses. I'll give that some more
thought, though, as I do like the idea of a visual queue that you're
in screen or tmux escape mode...

This bug was fixed in the package byobu - 5.9-0ubuntu1

---------------
byobu (5.9-0ubuntu1) precise; urgency=low

  * usr/bin/byobu-status:
    - fix broken status expiration, which wasn't working and probably
      had a huge performance penalty :-(
  * usr/bin/byobu-ctrl-a, usr/share/byobu/keybindings/f-keys.tmux,
    usr/share/byobu/keybindings/f-keys.tmux.disable,
    usr/share/byobu/profiles/tmuxrc: LP: #923134
    - get byobu-ctrl-a working within tmux, like screen
    - prompt the user for ctrl-a to work in Screen/escape mode, or emacs
      mode
